수성 고분자 - 탄소나노튜브 복합 분산 용액을 이용한 전계 방출 소자의 제작
초록
A polymer-based multi-walled carbon nanotube (MWCNT) field emission device was fabricated from a composite dispersion of MWCNTs and waterborne polymethyl methacrylate (PMMA). The waterborne PMMA synthesized through the emulsion polymerization method was added to minimize the reagglomeration of dispersed MWCNTs with surfactants in water, and increase the adhesion between the and the substrate. The field emission properties of the fabricated device were optimized by adjusting the density of the emitter and the adhesion between the MWCNTs and the substrate. These were done by controlling the polymer concentration added to the MWCNT dispersion, as well as the amount of spray coating on the substrate. The results confirm the successful fabrication of a polymer-based MWCNT field emission device with a low field of 1.07
