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)。

其他說明

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)。
