摘　　要：本文将自制Y式玻碳电极拉上两性接枝星形聚合物(GPSMA)的LB膜,用循环伏安法研究谈膜的屏蔽效应,讨论了接枝量、成膜条件等对膜缺陷的影响,并提出了减少缺陷的办法。The shielding effect of amphiphilic graft star polymer on Y-type glassy carbon electrode was studied by cyclic voltammetry. The experimental results showed the relationship between shielding effect and degree of branching, and the condition of film formation. The factors are discussed for estimating the film defect.
