摘要

本研究利用自由基不終止聚合反應，出4-(N,N-DiethyldithioCarb-
amylmethyl)benzyltrimethylammonium Bromide 作為Clay Pk-802之改質劑，使Clay成為改值過後的有機黏土，添加壓克力酸使蒙脫土達到完全剝離之狀態。加入不同的高分子中(Nylon 6 / Nylon 66)成為奈米複合材料並加以探討其熱性質、機械性質、阻水氣性質分析。

另外由於太陽能電池會因為太陽光長期的照射下，造成UV吸收峰會下降，本研究利用矽氧烷基的耐熱性極佳，加入導電高分子(Thiophene)裡，用H-NMR與GC/MS去鑑定成為新穎的導電高分子，用UV-VIS去比較上升溫度與常溫下的變化分析。

The exfoliated Nylon-Clay nanocomposites are synthesized in this research. They are fabricated by adding the polyacrylic acid nanocomposites, which are obtained by living free radical polymerizations.

The effect of mixing time on the mechanical properties of Nylon composites are investigated with FTIR. The effect of mixing time on the physical properties of Nylon 66 is more severe than those of Nylon 6.

Different conducting polymers are also synthesized in this research. A new thiophene material can be used in solar cells for thermal resistant applications.
