一般描述

聚乙烯吡咯烷酮[聚(N-乙烯-2-吡咯烷酮),PVP]是一种稳定的、大分子、无毒的非离子型聚合物。广泛应用于医疗、工业、制药、食品、化妆品和电子行业。可通过N-乙烯-2-吡咯烷酮的自由基聚合反应形成。

应用

聚乙烯吡咯烷酮(PVP)可作为:
  • 金属纳米颗粒(NP)合成的稳定剂,因为其疏水碳链产生的排斥力可防止纳米粒子团聚。
  • 作为杆状羟磷灰石(HAp)纳米粒子合成中的封端剂,控制羟磷灰石晶体的成核和生长。
  • 在制药行业中用作药物分散和悬浮的合成聚合物溶媒。
  • 溶液聚合的乳化剂和崩解剂

其他说明

聚乙烯吡咯烷酮是 Denhardt′s 溶液的一种成分,在标准 50X 储备溶液中的浓度为 1%(w/v)。
