一般說明
聚 （N-异丙基丙烯酰胺）（PNIPAM） 是一种具有低临界溶解温度（LCST)）的温度敏感型聚合物。在低于和高于 LCST 下它具有疏水和亲水特性。它通常通过自由基沉淀聚合形成微凝胶。
聚 （N-异丙基丙烯酰胺）（PNIPAM） 是一种用于生物医学研究应用的温度响应型聚合物。当加热到 32 °C 以上时，PNIPAM 经历可逆的低临界溶解温度（LCST)）相变，由可溶性材料转变为不溶性材料。PNIPAM 也经常进行交联以产生具有可逆、热收缩和膨胀的水凝胶。聚 （N-异丙基丙烯酰胺）也易于官能化，并已在热响应性两亲性嵌段共聚物的合成中用作亲水嵌段。由于 PNIPAM 的 LCST 温度与人体温度相似，PNIPAM 材料常被用于组织工程和受控药物递送研究应用。
應用
PNIPAM 可用于形成智能水凝胶，智能水凝胶可用于传感器、燃料电池、超级电容器和锂离子电池。它还可用于制造分子纳米温度计。 PNIPAM 表面涂布金纳米粒子 （AuNP） 以形成微凝胶，微凝胶有助于形成表面增强拉曼散射 (SERS) 的高度可重复信号。
热敏聚合物可用于形成水凝胶。当温度升至ca. 32 °C时，聚合物水溶液发生相变，即从可溶状态转变为不溶状态。
