一般說明
聚乙烯吡咯烷酮（polyvidone、povidone或PVP）是一种由线性1-乙烯基-2-吡咯烷酮基团组成的合成水溶性聚合物。它是吸湿性的，并且很容易吸收其重量的40%的水。它在溶液中具有优异的润湿性能，易成膜，适合用作涂料添加剂。PVP可以AIBN为引发剂，通过其单体形式N-乙烯基吡罗烷酮的自由基聚合合成。在化学品行业，PVP是应用广泛的表面稳定剂、生长调节剂、纳米颗粒分散剂和还原剂。
根据合成条件不同，PVP可用作表面稳定剂、生长调节剂、纳米颗粒分散剂和还原剂。

應用
PVP（平均分子量）可作为稳定剂，用于合成金属纳米颗粒，以防止其团聚。PVP还用于制备介孔硅聚合物杂化物(PVP-氨基丙基- sba -15希夫碱杂化物)，以有效去除废水中的二价重金属阳离子。PVP功能化的接枝对重金属离子具有很强的亲和力，因为它提供了两个吸附位点，一个是通过金属-C-O基团相互作用，另一个是通过金属-π相互作用（与希夫碱的螯合）。

Colloidal synthesis offers a route to nanoparticles (NPs) with controlled composition and structural features. This Perspective describes the use of polyvinylpyrrolidone (PVP) to obtain such nanostructures. PVP can serve as a surface stabilizer, growth modifier, nanoparticle dispersant, and reducing agent.
