一般描述
聚乙烯亚胺（PEI）是一种具有正电荷密度的聚合物。它具有多种用途，例如在水净化、造纸工业、以及从蛋白质溶液中去除核酸等。该聚合物首先用于DNA和寡核苷酸的递送。它也可以用作转染试剂。 硅胶经PEI化学修饰后可用作吸附剂。 PEI可稳定高表面积固体以吸附CO2。
应用
离子交换树脂
聚乙烯亚胺可用于TLC、纸色谱和LPLC的分离介质中。硅胶上的聚乙烯亚胺可用于薄层色谱法。

Samples of porous, foam-like TUD (Technische Universität Delft)-1 mesoporous silica were functionalized with polyethylenimine and were used as a substrate for CO(2) adsorption. Produced solids were characterized by means of electron microscopy, thermogravimetric analysis, and N(2) adsorption/desorption at 77K, in

The decontamination of synthetic Pb(II), Zn(II), Cd(II), Ni(II) solutions was investigated, using silica gels chemically modified with poly(ethyleneimine) (PEI) as sorbents. Two families of sorbents, i.e. silica/PEI and crosslinked silica/PEI, were prepared and characterized. Then the removal of metal ions
