Abstract:An ultra-thin metal based flexible transparent conductor was developed to offer advantages such as flexibility, low temperature processing, high electrical conductance and optical transmittance that can be tailored for different applications. It has already been applied to several types of optoelectronic devices, such as touch panels, electrochromic window, OLED and PVs. When used as transparent anode for OLED, it addresses a long-standing challenge of light trapping in OLED, which limits the device outcoupling efficiencies. In contrast to the commonly used ITO that has the highest refractive index within the OLED layer stack, thin-Ag based transparent anode can eliminate the waveguide mode, thereby liberating the light that otherwise trapped within the OLED layers. Its high conductance makes it ideal for large screen multi-touch applications. The transparent metal electrode can be advantageously applied to OPV by virtue of its low sheet resistance and adjustable reflectivity; and is also shown as a promising transparent conductor for perovskite PVs, promising cost advantages. It is also compatible with moisture barrier coating on plastic substrate, together the two can account for more than half of the material cost for future flexible perovskite PVs.

Abstract:Based on the fundamental scientific issues of nanomaterial preparation and functional inkjet patterning, a systematic Nano Green Printing technology has been developed. The precise control of the conversion from translational kinetic energy to rotational kinetic energy before and after droplet collision has been achieved using patterned wettability surfaces. This process breaks through the scope of classical Newton’s collision law and realizes a change in the motion mode of droplets before and after collision, providing new ideas for the preparation and precise control of high-precision patterns. Starting from the manipulation of droplets for three-dimensional shaping, spontaneous contraction of droplets in three-dimensional space has been achieved by using templates, enabling rapid assembly and shaping of three-dimensional micro/nano structures using multiple materials. Furthermore, the evolution of foam has been controlled using micro-templates, overcoming the long-standing challenge of patterned control of bubbles, and realizing the anti-Oswald ripening and patterning of bubbles. This has been used as a printing template for the assembly of multiple functional materials. In particular, by utilizing the advantages of droplet manipulation in nanoscale green printing, we discover the critical conditions for the scattering-diffraction transition of nano-photonic structures, an optical metamaterial detection chip has been developed for ultra-sensitive and rapid detection of novel coronavirus, influenza virus, and tumor markers. This opens up new ideas for the printing fabrication of functional devices and micro/nano chips, and establishes the theoretical and technical system of nanoscale green printing technology.

Abstract: The global electronics industry has embarked on the study of using additive manufacturing to replace photolithography in circuit manufacturing since the 1990s, such as screen printing, intaglio printing and inkjet printing. In 2010, the team of Suzhou NanoGrid Technology Co., Ltd. lead by Dr. Yulong Gao invented the new technology of preparing conductive circuits with embedded printing that achieved a printing resolution of 1.3 microns, based on which the manufacturing of flexible and transparent conductive films met large-scale application in the touchscreen industry. However, due to its dependency on silver ink, this technology has a setback that its resistivity after sintering is generally 6*10^-6 Ohm Meters, which is two orders of magnitude lower than that of pure copper (1.8*10^-8 Ohm Meters), while its cost is much higher than copper. In view that annual output of today’s printed circuit board (PCB) industry amounts to 700 billion RMB that has a high reliance on copper corrosion technology, green manufacturing of printed circuit boards at a low cost can only be achieved with a breakthrough in the additive manufacturing of pure copper. In 2015, Dr. Yulong Gao founded Shine Optoelectronics, where he and his R&D team finally realized the technological breakthrough in and commercialization of the embedded additive manufacturing of copper circuits through eight years of efforts and achieved a minimum copper circuit width of 500 nanometers. Today, the circuit boards made using this technology have been commercialized in the field of TV, and are heading toward more fields such as display, automotive and IC chip carrier.

Abstract: A new type of artificial-muscle fibers have been developed, and by adding twist, the length change of the fiber under humidity is amplified, and it is the first to develop smart responsive fabrics based on all-natural fiber materials such as silk with twisted structure. The artificial spider silk fiber with "twisted core-shell structure" was developed, which realized the multi-level structure of spider-like silk, and achieved the strength and toughness close to that of natural spider silk through organic polymer synthesis. The twisted structure reduces the entropy of the material and increases the refrigeration efficiency of the elastomer from 32% to 67%. A variety of elastic-thermal refrigeration materials based on twisted structure have been discovered, which expands the scope of solid-state refrigeration technology. An elastic conductor based on zero Poisson’s ratio pleat structure was developed, and the control of the conductive path was realized, and a resistive strain sensor with high linearity under 200% strain was prepared, which solved the problem of poor linearity under large deformation of resistive strain sensor. Based on this, an artificial muscle fiber with multi-level synergistic effect was constructed to simulate nerve conduction, strain sensing and drive.

Abstract: Lead halide perovskite nanocrystals are a luminescent material that is expected to be used in the next-generation display technologies that enables photoluminescence quantum yields close to 100%, narrow luminescence spectra, and easily tuneable luminescence wavelength. However, perovskite nanocrystals for light-emitting diodes are often synthesized through a displacement reaction that is difficult to control, resulting in low yields, uneven crystal growth, and poor stability. In order to synthesize high-quality perovskite nanocrystals for perovskite quantum dot (QD) light-emitting diodes, we propose a synthesis strategy for uniform growth and nucleation, which allows the control of nucleation and growth during synthesis by eliminating the nucleation-affecting clusters while inhibiting the overgrowth of Ostwald ripening to synthesize perovskite nanocrystals with narrow size distribution, few defects and highly controllable size. Specifically, we avoided the formation of PbX2 clusters by using Lewis acids and bases with relatively high dissociation coefficients as precursor ligands. After nucleation, a growth-inhibiting reagent is added to the synthesis system that also regulates the reaction equilibrium and passivates the nanocrystals. Through our synthesis strategy, the photoluminescence quantum yield and stability of red and green perovskite nanocrystals have been significantly improved and stable and efficient green and red lead halide perovskite nanocrystals were synthesized. The prepared QDs achieved an external quantum efficiency of 24.13% at 517/17 nm and 25.80% at 646/40 nm, and achieved pure red emission with an efficiency of 26.04%, with a luminous wavelength and an FWHM of 628/33 nm. The green perovskite LEDs achieved a record lifetime of 54 minutes at 10,000 cd/m², while the red perovskite LEDs had a 70-fold increase in stability, and the pure red perovskite QDs had a lifetime of 729 minutes at 1,000 cd/m2.

Abstract: Soft bio-integrated electronics have attracted great attentions due to the advantages of soft, lightweight, ultrathin architecture, and stretchable/bendable, thus has the potential to apply in various areas, especially in the field of biomedical engineering. By engineering the classes of materials processing and devices integration, the mechanical properties of the flexible electronics can well match the soft biological tissues to enable measuring bio signals and monitoring human body health.

For instance, we will discuss a wireless, battery-free platform of electronic systems and haptic interfaces capable of softly laminating onto the skin to communicate information via spatio-temporally programmable patterns of localized mechanical vibrations. The resulting technology, which we refer as epidermal VR, creates many opportunities where the skin provides an electronically programmable communication and sensory input channel to the body, as demonstrated through example applications in social media/personal engagement, prosthetic control/feedback and gaming/entertainment. Other demonstrations will include skin-interfaces human machine interface for robotic VR, skin like patches as sensors for healthcare monitoring and energy harvesting, etc.
