我们致力于为您带来更加绿色的替代产品，这些产品遵守一项或多项绿色化学12项原则。本品属于绿色替代产品的赋能型产品，符合“节能设计”原则。点击此处以获取更多信息。
聚(4-乙烯基苯酚)(PVP)是一种可成膜的聚合物交联剂，形成的无毒性、低成本薄膜可提高粘度。它是一种酸性聚合物，单个PVP分子含100多个羟基，因而形成的膜具有高度的稳定性和络合度。

應用

交联PVP可用作介电材料，制备低电压单壁碳纳米管(SWCNT)基质的薄膜晶体管。有机半导体薄膜晶体管采用具有光电阻性的PVP作为势垒层 ，其上可涂覆各种带电荷纳米颗粒，如银纳米颗粒(AgNP)、氧化钛(TiO2)和氧化石墨烯(GO)。
用作光致抗蚀剂中酚醛树脂的替代物，助粘剂，并且可以提高热熔胶的耐热性，改善金属表面精整的表面处理。用作塑料中的抗氧化剂和阻燃剂的衍生物。聚合物混合物的组分，从而改变表面特性并提高抗冲击性。
