폴리아크릴로니트릴로 강화한 탄소나노튜브 복합체 시트

초록

In this study, the effects of polyacrylonitrile (PAN) impregnation on the electrical and mechanical properties of a carbon nanotube (CNT) sheet/PAN composite were investigated. The CNT sheet was synthesized via chemical vapor deposition and used without chemical treatment. PAN was incorporated into the CNT sheet for load transfer between the CNT bundles. It was confirmed, via Raman spectroscopy, that there was no damage to the CNT structure and that the mechanical properties of the CNT/PAN composite had improved. Although an insulated polymer was used in the composite process, the composite showed relatively high conductivity, which appeared to be due to the capillary force induced by dimethyl sulfoxide (DMSO) evaporation.
