本實驗主要為合成並探討具備光活性與電活性兩種性質之聚亞醯胺高分子,並結合表面帶有胺基官能基之奈米碳管以合成奈米複合材料,並進行一系列的物性探討。 首先,將帶有光活性性質之偶氮苯衍生物與帶有電活性性質之胺基封端苯胺三聚體(Amine-capped aniline trimer;ACAT),利用氧化偶合反應製備出偶氮苯衍生物在側鏈且胺基封端苯胺三聚體在主鏈的光電活性聚亞醯胺高分子。另一方面,以Friedel-Crafts acylation reaction方式改質多壁奈米碳管,使碳管表面帶有胺基,將其與光電活性聚亞醯胺高分子利用氧化偶合反應,合成光電活性聚亞醯胺/奈米碳管複合材料。 單體的部分,利用傅利葉轉換紅外線光譜儀(FTIR)、核磁共振儀(NMR)與液相層析質譜儀(LC-MS)鑑定其結構。複合材料的部分,則以紫外光可見光光譜儀(UV-Vis)與循環伏特安培儀(CV)等儀器,探討(1)偶氮苯光異構化與熱異構化的變化情況;(2)偶氮苯光異構化(i.e., cis trans)對電活性高分子的影響;(3)電活性高分子之電活性。同時並探討光電活性聚亞醯胺高分子添加奈米碳管後,其對維生素C (Ascorbic acid,AA) 偵測能力的提升效益。
This experiment to explore with photoactive and electroactive two properties of polyimide polymer, and import the surface of an Amino-functionalized CNTs, and making a series of investigations. First, the nature of the photoactive with azobenzene derivative and the nature of electroactive with Amine-capped aniline trimer (ACAT) using the oxidative coupling polymerization reaction prepared azobenzene derivatives in the side chain, amine-capped aniline trimer in the main chain of the photoactively electroactive polyamide polymer。Next, Amino-functionalized CNTs grafted with photoactively electroactive polyamide polymer was obtained photoelectric activity polyimide/CNTs composites by Friedel-Crafts acylation of CNTs by direct electrophilic substitution reaction with 4-aminobenzonic acid (4-ABAD) using a mild and noncorrosive medium of polyphosphoric acid (PPA)/phosphorous pentoxide (P2O5). Monomer part, the use of FTIR, NMR, LC-MS identification of its structure. Polymer composite material part, places UV-visible and CV to explore (1) azobenzene photoisomerization and thermal isomerization changes; (2) azobenzene photoisomerization (i.e., cis trans)effect on the electrical activity of the polymer; (3) electro-active polymer of the electrical activity. At the same time explore the optical activity of polyimide polymer adding MWCNTs, its vitamin C (Ascorbic acid, AA) detection capabilities.
