羟丙基纤维素 (HPC) 在性质上具有生物相容性，并显示出较低的临界溶液温度 (LCST)。它是由纤维素与碱反应，生成碱纤维素，再与环氧丙烷连续反应制得的。HPC 溶于水，溶解度低于室温，粘度与温度呈反比关系。 应用 HPC 骨架组成的共聚物与 聚（2-二甲氨基）乙基甲基丙烯酸酯侧链已被合成用于基因传递。HPC 已被用作纳米结构锐钛矿膜的粘合剂。由 HPC 骨架和聚（N-异丙基丙烯酰胺）作为侧链制成的聚合物缀合物充当智能水凝胶。已有报告称 HPC 被作为胶水进行研究。 Hydroxypropyl cellulose (HPC) is biocompatible in nature and exhibits low critical solution temperature (LCST). It has been reported to be prepared by reacting cellulose with alkali, producing alkali cellulose which is consecutively reacted with propylene oxide. HPC is soluble in water at lower than RT. Viscosity behaves inversely to rise in temperature. Application Copolymers composed of HPC backbones with poly((2-dimethyl amino)ethyl methacrylate side chains has been synthesized for gene delivery. HPC has been used as a binder in to nanostructured anatase membranes. Polymer conjugates made of HPC backbones and poly(N-isopropylacryamide) as side chains act as smart hydrogels. HPC has been reported to be studied as a glue.
