Furthermore, the relationships among degree of miscibility, morphology and mechanical properties of polyblends and grafted copolymers are constructed. The mechanicism of proton transfer , structure of modified polyurethane and polyaniline and microstructure of the synthesized grafted copolymers and polyblends are characterized by 13 C NMR, TEM and AFM. The mechanical properties of the synthesized copolymers are included of storage modulus and loss modulus. Combing experimental results, the roles and relationships among degree of ionic sulfonation, miscibility, morphology, mechanical properties of the materials are investigated.application/pdf1435539 bytesapplication/pdfzh-TW國立臺灣大學化學工程學系暨研究所聚胺酯聚苯胺磺化聚摻合接枝共聚物PolyanilinePolyurethaneSulfonationPolyblendGraft Copolymerreporthttp://ntur.lib.ntu.edu.tw/bitstream/246246/9396/1/922216E002012.pdf
