摘要：

Mechanism of citrate alkaline copper electrodeposition in presence of polyethyleneimine was researched.Tested by SEM,It's propitious to obtain fine and symmetrical copper film at wider current densities with polyethyleneimine.XRD analysis indicated copper deposits exhibited growth orientation of crystal face(111),which remained with parallel growth.Cyclic voltammograms results indicated that polyethyleneimine adsorbing preferentially at cathode high current density area could make a stronger inhibition on copper electrodeposit.Studied by chronoamperometry,it's showed that initial stage behavior of copper electrodeposition belonged to diffusion controlled and three-dimensional progressive nucleation.
