Abstract
This study is mainly to discuss the positive temperature coefficient (PTC) effect of Polymer Conductive Composite (PCC), which includes the preparation for Ni composite particle, polyimide and polystyrene-co- butylacrylate matrix, particularly the temperature-resistance behavior of composite films. What would be the impact to PTC feature for composite film, by changing the combination of above factors, as well as the process, is our major interest in overall study. The study consists of 3 main topics: Part I. Micro Ni-plated SiO2 particle/polyimide matrix system Part II. Core-shell type P(S-DVB) Ni-plated particle/P(S-co-nBA) matrix system Part III. The thickness-direction PTC feature of micro Ni powder/ polyimide matrix system
