用一系列表面活性吡咯衍生物研究了吸附单体在水- 1,2-二氯乙烷界面上的聚合反应。聚合反应是由溶解于有机相的单体与溶解于水相的Ce(SO)(4)之间的电子转移反应引起的。在可转移离子存在的情况下，通过表面张力测量和循环伏安法监测界面上聚合物层的形成。研究发现，与简单的吸附层相比，存在聚合物层的界面张力与施加电位无关，并且聚合物层强烈抑制离子转移反应。(C) 2001 Elsevier Science B.V.版权所有
Polymerization of adsorbed monomers at the water 1,2-dichloroethane interface was studied with a series of surface active derivatives of pyrrole. Polymerization was induced by an electron transfer reaction between a monomer dissolved in the organic phase and Ce(SO)(4) dissolved in the aqueous phase. The formation of a polymer layer at the interface was monitored by surface tension measurement and by cyclic voltammetry in the presence of transferable ions. It was found that in contrast to a simple adsorbed layer, an interfacial tension in the presence of a polymer layer becomes independent of the applied potential and that a polymer layer strongly inhibits ion transfer reactions.
