【摘要】 本文采用自由基共聚原理制备了网状结构的聚（丙烯酸/丙烯酰胺）（P（AA/AM））基体树脂,引入乙酸1-乙基-3-甲基咪唑鎓作溶剂,原位聚合得到离子液体质量分数为35%～70%的P（AA/AM）离子凝胶。所制备的离子凝胶中离子液体与P（AA/AM）良好相容,离子液体的加入降低了P（AA/AM）聚合物的短程有序性,导致形成完全的无定形结构,220℃以下热稳定性良好。离子液体含量为70%的P（AA/AM）离子凝胶,其拉伸强度为4.11MPa,电导率达0.315S·m^-1,且该P（AA/AM）离子凝胶对温度和拉伸形变有较高敏感度,20℃时的电阻温度系数为4.0%·℃^-1,可作为热传感器和柔性传感器监测人体关节运动。更多还原

【Abstract】 Poly（acrylic acid/acrylamide） ionogels were synthesized by introducing 1-ethyl-3-methylimidazolium ethyl sulfate into the P（ AA/AM） ross-linked polymer in radical copolymerization, while the mass fraction of ionic liquid changed from 35% to 70%. The ionic liquid is well compatible with P（AA/AM） in the synthesized ionic gel,and the short-range ordered of P（AA/AM） polymer is reduced or even formed a completely amorphous structure. It has good thermal stability within 220 ℃, the tensile strength of P（AA/AM） ionogel with mass fraction 70% of ionic liquid is 4. 11 MPa, and the conductivity is 0. 315 S·m^-1. P（AA/AM） ionogel is highly sensitive to temperature and tensile deformation, and can be used as a thermal sensor and flexible sensor to monitor human joint movement. The temperature coefficient of resistance at 20 ℃ is 4. 0%·℃^-1.更多还原
