Polyethyleneimine (PEI) imhando yepamusoro yepolymer inoumbwa ne ethyleneimine monomers.Nechimiro chayo chetani refu, PEI inoratidza yakanakisa yekunamira zvivakwa, zvichiita kuti ive sarudzo yakanaka kune akasiyana maapplication, anosanganisira mapeji ekuputira, machira, anonamira, uye pamusoro pekugadzirisa.Uyezve, PEI's cationic nature inoibvumira kuti inyatso sunga kune zvisina kunaka inochajiswa ma substrates, ichisimudzira mashandiro ayo mumaindasitiri akasiyana.
Pamusoro pezvimiro zvayo zvekunamira, PEI inoratidzawo hunyanzvi hwekuvharisa, hunobatsira munzvimbo dzakawanda dzakadai sekurapwa kwetsvina, CO2 kubatwa, uye catalysis.Huremu hwayo hwemamorekuru huremu hunobvumira kushanda uye kusarudzwa adsorption, zvichiita kuti ive chinhu chakakosha mukucheneswa kwemagasi uye zvinwiwa.
