Epoxy、Poly(lactide)及奈米光電材料之合成與性質研究
A study on polymer/clay composites and electro-optics materials
摘要
本研究論文第一部分複合材料。本研究主要是添加不同比例處理過後之蒙特土(montmorillonite)在高分子中，得到奈米複合材料。所添加的蒙特土須達剝離的狀態，才能使物性達到最佳的狀態。所以改質劑的挑選很重要。針對蒙脫土的改質劑，我們將自行合成，接著先與蒙脫土做離子交換初步將蒙脫土的層間距撐開，之後利用亞克力酸進行聚合反應，使蒙脫土的矽酸鹽層距離可以更進一步的擴大。希望得到高蒙脫土含量的高分子，並且剝離的奈米複合材料。 第二部分為可應用在太陽能電池、OLED…等光電材料方面的共軛高分子合成。以噻吩為主體，分別在其三號位置上導入矽氧烷及己烷基，形成3-ST(3-Siloxanylthiophene)及3-HT(3-hexylthiophene)，接著將這二者聚合形成共聚合物PSTHT(poly(3-Siloxanylthiophene-co- 3-hexyl-thiophene))，另外，取EDOT與3-HT也將這二著做聚合形成共聚物PEDHT(poly(3,4-Ethylenedioxythiop- hene-co-3-hexyl-th-iophene))。P3HT、PSTHT、PEDHT這三者共軛高分子以FTIR、TGA、GPC、UV/vis..等儀器來討論在其結構、光電性質上及熱性質的差異，期望在光電材料上有及應用價值。

Nanocomposites of clay-epoxy are studied in this research.The clay are exfoliated by acrylic acid living polymerization.The exfoliated nanocomposites are obtained with clay contents ranging from 1% to 10%. The tensile strength and glass transition temperature increase significantly after adding the clay. On the other hand,nanocomposites of clay-PLA are studied in this research.The clay are exfoliated by acrylic acid living polymerization.The exfoliated nanocomposites are obtained with clay contents ranging from 1% to 10%. The tensile strength and glass transition temperature increase significantly after adding the clay. Studies on the synthesis of conjugate polymers.Conjugate polymers,like poly(3-hexylthiophene)(P3HT),is an important conducting polymer because of its excellent optical properties. P3HT were synthesized by the oxidation coupling reaction of 3-hexylthiophene with anhydrous FeCl3 at room temperature in this study.We also synthetized (poly(3,4-Ethylenedioxythiophene-co-3-hexyl-thiophene))(PEDHT) and (poly(3-Siloxanylthiophene-co-3-hexyl-thiophene)) (PSHTH).Physical and chemical properities were measured and analyzed by FTIR、TGA、DSC、UV/vis…etc
