【摘要】：離子作用的可逆性賦予了含離子聚合物豐富的力學(xué)和電學(xué)性能,使其廣泛應(yīng)用在高抗沖材料、記憶材料、自修復(fù)材料和智能響應(yīng)材料等新興領(lǐng)域.本專論結(jié)合作者近年的研究工作,介紹了含離子聚合物體系的構(gòu)效關(guān)系和分子流變學(xué),從3個方面展開:第1部分介紹了對于含離子聚合物的離子聚集狀態(tài)的調(diào)控,和離聚物與聚電解質(zhì)的相互轉(zhuǎn)化;第2部分介紹了離子高度聚集的無規(guī)離聚物豐富的線性黏彈性,重點介紹了非纏結(jié)體系在鏈均一個離子濃度附近區(qū)域的溶膠凝膠轉(zhuǎn)變以及纏結(jié)體系在平均每個纏結(jié)鏈段一個離子濃度附近區(qū)域的單平臺到雙平臺模量的轉(zhuǎn)變;第3部分介紹了如何進(jìn)行分子設(shè)計,使得含離子聚合物成為有效的離子傳輸介質(zhì).最后總結(jié)了該研究領(lǐng)域的科學(xué)問題和面臨的挑戰(zhàn).
[Abstract]:The reversibility of ionic interaction gives ionic polymers rich mechanical and electrical properties, making them widely used in high impact materials, memory materials, This monograph introduces the structure-activity relationship and molecular rheology of ion-containing polymer systems in combination with the authors' recent research work, such as self-repairing materials and intelligent response materials. The first part introduces the regulation of ionic aggregation state of ionic polymers and the interaction between ionomers and polyelectrolytes, and the second part introduces the rich linear viscoelasticity of random ionomers with high ion concentration. The sol-gel transition of the non-entangled system in the region near the concentration of one ion per chain and the transition of the single-platform to the bi-platform modulus of the entangled system in the region near the average concentration of one ion per entangled chain are introduced. In the third part, we introduce how to design the molecule to make the ion-containing polymer become an effective ion transport medium. Finally, the scientific problems and challenges in this field are summarized.
