| Summary: | 碩士 === 雲林科技大學 === 化學工程與材料工程研究所 === 96 === The poly(imide siloxane) precursor were blended with Hexamethyldisilazane (HMDS) modified silica were synthesized through straightforward simultaneous condensation reaction of pyromellitic dianhydride (PMDA), 2,2’-bis[4-
(3-aminophenoxy) phenyl] sulfone (m-BAPS) andα, ω-bis (3-aminopropyl) polydimethyl siloxane(APPS). The prepared PIS copolymers possess the properties of thermal plastic elastomers. Microphase separation, affected by formulation, was found to be important phenomenon that determined the physical properties of the PIS copolymer.
The achievement of reinforcement by the incorporation of SiO2 in PIS matrix can be well reflected in mechanical properties of hybrid composites. Mechanical measurement with the tensile meter showed that the poly(imide siloxane)/SiO2 composites exhibited a good extension. These poly(imide siloxane)/SiO2 composites exhibited excellent rubber property. The thermal stability and mechanical properties were found to increase with increasing SiO2 content.
