温敏共聚物是指两个或两个以上共聚单体中至少有一个温敏组分的聚合物。当外界温度变化时,它们会发生快速可逆相转变行为,因此在化学和生物材料领域有潜在应用价值。聚(N-异丙基丙烯酰胺)(PNIPAM)系共聚物是目前研究最多的一类温敏共聚物。综述了聚N-异丙基丙烯酰胺系温敏共聚物制备和应用方面的研究进展,并对未来发展方向进行了展望。
Temperature-sensitive copolymers are polymers of at least one temperature-sensitive component of two or more comonomers. When the external temperature changes, they will happen fast reversible phase transition behavior, so in the field of chemical and biological materials have potential applications. Poly (N-isopropylacrylamide) (PNIPAM) copolymer is currently the most studied type of temperature-sensitive copolymer. The research progress on the preparation and application of poly (N - isopropylacrylamide) temperature - sensitive copolymer is reviewed. The future development is also forecasted.
