Self-assembly assisted Stretchable Energy Storage/Transparent Electrodes
손정곤 한국공업화학회 2020 한국공업화학회 연구논문 초록집 Vol.2020 No.-
Stretchable electronics, which require the stretchability necessary to endure complex motions from humans, have recently attracted considerable attention for bio-implantable and wearable devices. In this talk, we suggest several self-assembly based approaches for structure-assisted stretchable transparent/energy storage electrodes. We firstly introduced an ideal stretchable Ag NW network nanostructure consisting of in-plain wavy Ag NW strands with large radius of curvature by a floating-compression process like Langmuir-Blodgett self-assembly. The second part, we introduce novel 2D reentrant cellular structures of porous graphene/CNT networks for omnidirectionally stretchable supercapacitor electrodes. The 2D reentrant structures of graphene/CNT networks maintained excellent electrical conductivities under biaxial stretching conditions and showed a slightly negative or near-zero Poisson’s ratio over a wide strain range because of their structural uniqueness.

These Days a lot of Noise Complaints in vicinity of Railway has been more increase than before. Almost 1/3 Residences who lives in Railway side are Exposure to Noise Pollution. Since the Apartment Buildings around Railway are getting more higher ,so those of the Noise Barrier are not best solution anymore. We are going to make a New Plane with the state of the art technology for Railway Noise Abatement Control. Our Goal are focus on a development of Light Weight Noise Tunnel designed by new absorption matl and tunnel Stucture on the Overbridge and Viaduct of existing Railway. New Noise Tunnel will be reducing their weight more than 30% against Road Traffic One and also 10dB(A) Noise Reduction against Noise Barrier.
