| Summary: | 碩士 === 長庚大學 === 化工與材料工程研究所 === 94 === The purpose of this study is to synthesize porous PAn composites (PAn/Clay) with nano-scale and to investigate their structural and physical properties and their thermal degradation after closslinking with epoxy resin. Porous PAn composites with different pore size and surface area were obtained by changing the weight ratio of PAn/Clay. It was found that PC11 composite has inter-layered structure by X-ray diffractometer. The composition of PAn and montmorillonite could be analyzed the arrangement of PAn and FT-IR. The particle size and pore size of the composites were decreased with increasing the contents of PAn, whereas the pore volume increased as analyzed by BET and FE-SEM.
The Tg and ΔH of closslinked PAn with expoxy resin were increased and decreased with increasing of PAn contents, respectively, as measured by DSC. Their activation energy and reaction order of thermal degradation were also increased with increasing the contents of PAn as analyzed with TGA. The performance of anti-combustion of the composites increased with the addition of PAn as shown by the limit oxygen index (LOI) test.
