聚三氮唑高分子功能材料 張衛(wèi)懿 1,* 1東華大學(xué)，上海市松江區(qū)人民北路2999號(hào)，201620 *Email: wyzhang@dhu.edu.cn 聚離子液體（PILs）高分子是一種以離子液體為前體的新型聚電解質(zhì)材料，最初在20世紀(jì)90年代開(kāi)始被開(kāi)發(fā)出來(lái)并開(kāi)始研究。與傳統(tǒng)的聚電解質(zhì)材料相比，聚離子液體具有玻璃化轉(zhuǎn)變溫度低，在有機(jī)溶劑中溶解性好，導(dǎo)電性提高的特點(diǎn)。近年來(lái)，隨著各個(gè)領(lǐng)域?qū)Ω叨瞬牧系囊笕找嫣岣撸铣晒δ苄愿叻肿映蔀榱颂嵘嚓P(guān)材料性能的有力途徑，其中就包括功能性聚離子液體。因此，我們開(kāi)發(fā)出了一種新型的三氮唑類聚離子液體高分子材料。此類材料表現(xiàn)出了非常獨(dú)特的化學(xué)性質(zhì)和膠體特性，特別是在之后的研究中發(fā)現(xiàn)三氮唑類聚離子液體在弱堿條件下會(huì)生成聚卡賓結(jié)構(gòu)，能被用于穩(wěn)定金屬簇，和制作梯度卡賓-膜驅(qū)動(dòng)材料。另外，離子液體被作為儲(chǔ)能器件的電解質(zhì)部分研究已久，由于其異常寬的電化學(xué)窗口，能帶來(lái)很高的儲(chǔ)能密度，同時(shí)由于其較低的凝固點(diǎn)（某些離子液體凝固點(diǎn)低于零下50度），能被用于低溫儲(chǔ)能。聚離子液體在繼承離子液體大部分性質(zhì)的同時(shí)還有高分子的優(yōu)點(diǎn)（柔性，易塑型等），因而可用作儲(chǔ)能器件的固態(tài)電解質(zhì)。回國(guó)之后也開(kāi)展了一些新結(jié)構(gòu)的離子液體/聚離子液體的設(shè)計(jì)合成，嘗試打通結(jié)構(gòu)-設(shè)計(jì)-性質(zhì)-性能的一條鏈。 Fig. 1 Synthesis of Poly(1,2,4-triazolium)s and its behavior in metal ion loading 關(guān)鍵詞：聚離子液體；聚電解質(zhì)；三氮唑；聚卡賓 參考文獻(xiàn) [1] Zhang, W.; Yuan J.*, et al., ACS Nano, 2016, 10, 7731.

Functional Poly(1,2,4-triazolium) Materials Weiyi Zhang1,* 1College of Materials Science and Engineering, Donghua University, 2999 North Renmin Road, Shanghai, 201620 *Email: wyzhang@dhu.edu.cn Abstract text in English, Times New Roman, 300 words maximum Poly(ionic liquid)s (PILs) are one new type of polyelectrolyte materials that acquired from ionic liquids as polymerization precursors. They were first developed and studied in the 1990s. Compared with traditional polyelectrolyte materials, poly(ionic liquid)s have the unique characteristics of low glass transition temperature, good solubility in organic solvents, and improved conductivity. In recent years, with the increasing requirements for high-end materials in various fields, synthetic functional polymers have become a powerful toolbox to improve the performance of related materials, including functional poly(ionic liquid)s. Therefore, we have developed a new type of 1,2,4-triazolium-based poly(ionic liquid) polymer material. Such materials exhibit very unique chemical properties and colloidal properties. In particular, it was found in subsequent studies that triazole-based poly(ionic liquid)s can generate polycarbene structures under weak alkaline conditions, which can be used to stabilize metal clusters, and be made into gradient carbene-membrane actuators. In addition, ionic liquids have been studied for a long time as the electrolyte part of energy storage devices. Due to their unusually wide electrochemical window, they can bring high energy storage density. At the same time, due to their low freezing point (some ionic liquids have a freezing point lower than Minus 50 degrees), can be used for low temperature energy storage. While inheriting most of the properties from ionic liquids, poly(ionic liquid)s also benefit from the advantages of polymers (flexibility, easy plasticity, etc.), so they can be used as solid electrolytes for energy storage devices. After back to Donghua University as a Principal Investigator, I am trying to design and synthesize ionic liquids/poly(ionic liquid)s with new structures, and aiming for the study of structure-design-property-performance relations.
