Novolac-based poly(1,2,3-triazolium)s with 1,2,3-triazolium side groups spaced by oligo(ethylene glycol), a new kind of poly(ionic liquid) membrane, was prepared the well-known Click chemistry (1,3-dipolar cycloaddition reaction). The thermal properties, ionic conductivity and gas permeation performance of these self-standing membranes were investigated. The obtained membranes exhibit glass transition temperatures ranging from -1 °C to -7.5 °C, and a temperature at 10% weight loss above 330 °C. These membranes have good ionic conductivity ( up to 5.1 × 10 S cm at 30 °C under anhydrous conditions) as compared with the reported 1,2,3-triazolium-based crosslinked polymers. And they could be potentially used for CO separation as they exhibit enhanced CO permeability up to 434.5 barrer at 4 atm pressure.
基于酚醛清漆的聚（1,2,3 - 三唑鎓），其1,2,3 - 三唑鎓侧基由低聚（乙二醇）隔开，是一种新型的聚（离子液体）膜，通过著名的点击化学（1,3 - 偶极环加成反应）制备而成。研究了这些自支撑膜的热性能、离子电导率和气体渗透性能。所获得的膜表现出玻璃化转变温度范围为 -1°C至 -7.5°C，以及在330°C以上10%重量损失时的温度。与报道的基于1,2,3 - 三唑鎓的交联聚合物相比，这些膜具有良好的离子电导率（在无水条件下，30°C时高达5.1×10 S cm）。并且由于它们在4个大气压下表现出高达434.5巴每尔的增强的CO渗透性，因此它们有可能用于CO分离。
