분리된 네트워크를 통한 고전도성 탄소나노튜브 복합재료를 히팅층으로 갖는 온디멘드 레이저 프린터 개발

초록

The printing fuser is exposed under a mechanically and thermally harsh environment, as the temperature goes above the melting temperature of toner within just a few seconds, which means that the fusing system can be a good test bed to see the effect of TCR (temperature coefficient of resistance) reduction on stabilization of supplying power. The MWCNT (multiwalled carbon nanotube)-based composite fuser was built as heating element in a real printer (Fig. 1), which can heat and fuse toners on papers at above the toner melting point (around 180?C). Segregated carbon nanotube network induced by excluded volume with micro-silica (SiO2) and nano-silica (nSiO2), respectively, were used for the suppression of the resistance change.
