Recently, the team of Wu Zhongshu, a researcher from DNZ21T3 group, Institute of Advanced 2D Materials and Energy Devices, Dalian Institute of Chemical Physics, Chinese Academy of Sciences, has made new progresses in the research of flexible and miniaturized graphene based supercapacitors and successfully obtained 2D Thiophene nanosheets and graphene laminated composite films, and applied to high performance, flexible, miniaturized supercapacitors. Relevant research results published in the "Advanced Materials" magazine (DOI: 10.1002 / adma.201602960).
In recent years, with the highly integrated, lightweight portable, wearable, implantable and other new concepts, especially the concept of flexible electronic products constantly put forward, there is an urgent need to develop highly compatible with its high energy density, Flexible, functional integration of micro-energy storage devices. To achieve this goal, the team successfully synthesized graphene based high power planar micro supercapacitors by combining methane plasma reduction and photolithographic micromachining in a previous study (DOI: 10.1038 / ncomms3487). The graphene films doped with nitrogen and boron co-doped by layer-by-layer self-assembled graphene oxide and polylysine with intercalation of boric acid were applied to micro-supercapacitors (Acv. Mater. 2014, DOI: 10.1002 / adma.201401228); high density, high conductivity polymer / graphene, activated graphene / graphene thin film materials are prepared by alternate stacking method, Micro Flexible Supercapacitor (Adv. Mater. 2015, DOI: 10.1002 / adma.201501643); Graphene conductive polymer film is prepared by spray coating method, which is used in ultra-thin, printable and ultra- Capacitors (Adv. Mater. 2015, DOI: 10.1002 / adma.201501208). These flexible, miniaturized supercapacitors represent important applications for future electronics (Natl Sci. Rev. 2014, DOI: 10.1093 / nsr / nwt003).

Paint Surface Series PETG Film
Paint surface PETG Film is a high-quality surface decoration material widely used in the furniture industry. It has the following characteristics:
1. Scratch resistance: The paint surface PETG film adopts special surface treatment technology, making it have high scratch resistance performance. Even in daily use, it can effectively prevent scratches and scratches, and maintain the smoothness and aesthetics of the furniture surface.
2. Oil stain resistance: The paint surface PETG film has excellent oil stain resistance performance. Even if oil spills onto the surface of furniture, it can be easily wiped clean without leaving any marks or stains.
3. Anti fingerprint: The paint surface PETG film adopts special coating technology, which can effectively resist the adhesion of fingerprints. Even if your fingers touch the surface of the furniture, they will not leave obvious fingerprints, maintaining the cleanliness and aesthetics of the furniture.
4. Waterproof: The paint surface PETG film has excellent waterproof performance. Even if soaked or splashed with water, it will not penetrate into the interior of the furniture, protecting its quality and lifespan.
In short, the paint surface PETG film has the characteristics of scratch resistance, oil resistance, fingerprint resistance, and waterproofing, making the furniture surface more durable, easy to clean, and able to maintain long-term aesthetics. It is an ideal surface decoration material for furniture and has been loved and favored by a large number of consumers.
