Polyaniline/polyurethane copolymers and semi-IPNs were investigated into nanostructure, themal analysis, mechanical properties and the mechanisms of gas separation. Polyaniline/polyurethane copolymers are composed of soft segmental structure from polyol, hard segmental structure from isocynate and amine-terminated oligomeric polyaniline of various segmental chains as chain extenders. The repeated units of aniline in oligomeric polyaniline is between 3 to 10. Oligomeric polyaniline dopped with protonated acid was to investigate the effects on conductivity of various segmental chains in the copolymers and semi-IPNs. The nanostructure of polyaniline/polyurethane copolymers are characterized by NMR, TEM , SEM and AFM ; The thermal analysis of the copolymers include LT-MDSC and TGA ; The mechanical properties of the copolymers include tensile strength, etc.;The mixing gases for gas separation included the pairs of CO2/CH4 and O2/N2. The characteristics of membrane separation mainly include gas permeability, gas selectivity, diffusion coefficient and solubility of gases. Therefore,by integrating all the research results, the effects of the nanostructures on the conductivity and the characteristics of membrane separation were investigated completely.本研究宗旨在合成及鑑定聚苯胺/聚胺酯共聚合物及其 高分子網狀結構體，並探討聚苯胺/聚胺酯共聚合物及其高分 子網狀結構體薄膜熱性質分析、混合氣體分離效應與機械性 質，並進而探討薄膜奈米結構、薄膜分離特性與機械性質的 相關性。聚苯胺/聚胺酯共聚合物的組成主要包含軟鏈段的聚 醇、硬鏈段的異氫酸鹽與不同鏈段之苯胺寡聚合體為鏈延長 劑，其結構的控制乃藉由鏈延長劑鏈段長短做調整，其鏈段 之重複單元介於3~10 。摻雜質子酸之苯胺寡聚合物主要探討 不同鏈段之鏈延長劑對聚合物導電特性的影響。合成聚苯胺 /聚胺酯共聚合物微相相分離結構的鑑定主要經由核磁共振 光譜（NMR ）、穿透式電子顯微鏡（TEM ）及原子力場顯微 鏡（AFM ）等儀器分析;機械性質包含機械強度、彈性模式 及損失模式等;熱性質分析包含低溫調幅式示差掃描熱卡計 (LT-MDSC )、熱重損失分析儀(TGA );混合氣體包含 CO2/CH4 、O2/N2 ，薄膜分離特性主要有氣體對薄膜透氣量、 選擇率、擴散係數及溶解度。綜合研究結果，分析奈米尺度 之奈米結構、導電特性、薄膜在氣體分離特性與機械性質的關聯性。application/pdf416905 bytesapplication/pdfzh-TW國立臺灣大學化學工程學系暨研究所reporthttp://ntur.lib.ntu.edu.tw/bitstream/246246/9350/1/912216E002018.pdf
