The main research subjects include recycling saccharide-based polymers for the wearable electronic components; refining lignin or cellulose from the non-food/food wastes for printed electronic substrates or packaging films; and preparing ester-carbonate copolymers through the chemical recycling of CO2 with the chemical intermediate recycled from polyethylene terephthalate (PET). [Energy materials] (C&D): Develop key technologies for new generation of renewable energy and energy storage. We focus on developing high performance materials and process for the next generation solar cells, including the single-crystalline thin-film preparation of lead-free perovskite; exploitation of environmentally friendly solar electro-catalytic non-Pt materials; dye-sensitized solar cells with a green fabrication process; and fast and energy-efficient atmospheric plasma process. Also, the solar cells could be used to produce hydrogen efficiently for high performance fuel cells. Next, key materials and processing technologies are developed for the high-capacity Li-ion battery including the exploitation of materials for cathode/anode, separation membranes, electrolytes, surface modification, device integration, and the application valuation on electric cars. [Green electronic materials] (E): The research focuses on the green electronic processes, including recycling Si wastes; exploiting SiO materials for energy storage and the green process for the SiCl4 and TEOS key materials for semiconductors; establishing the waste reduction and recycling technology on the electro/ plating processes; and fabricating high color rendering and wide color gamut with LED quantum dots. Our developed technologies include (1) biomass based conductive films and their electronic devices, (2) multifunctional applications of celluloses, (3) recycling PC and PET for high valued-added materials, (4) interfacial layer for high capacity and safe energy storage cells, (5) recycling silicon materials for high valued-added materials, (6) membrane key technology for circular economy, (7) green process for high color rendering and wide color gamut with LED quantum dots. The research achievements of the 2018～2019 are described in the following: 135 SCI journal papers and 94 of them are in the top 15% ranked journal category; 3 granted patents and 14 applied patents; 40 industrial collaboration projects and technology transfer with the total grant of 48740000 NTD; 25 items of industrial investment with the total budget of 131525000NTD and two ongoing start-up company; cultivate 12 high level researchers; 18 forum/workshop/conference; and establish the green materials international research hub with the institutes from France, Japan, and Australia. In the future, we will devote to develop the leading green materials technology and cultivate high-level researchers with a strong industrial collaboration.
