Its hydrophilic groups is the inside carbonyl and amine base, and its lipophilic groups is the inside hydrocarbon chain and outer methyl. PAMAM of integral generation basically has not the surface activity. Its reason is that its outer groups is acylamino groups having very strong hydrophilicity so as not to reduce the surface tension of water. PAMAM different from traditional surfactant, have not critical micelle concentration, and exist in the form of "unimolecule micelle" in water.

结果表明：半代的PAMAM水溶液的表面活性与其分子具有两亲结构有关，亲水基团是内部的羰基和胺基，亲油基团是内部的碳氢链和外层的甲基；整代的PAMAM水溶液基本上没有表面活性，其原因是其最外层基团是酰胺基，亲水性很强，不能降低水的表面张力；树状大分子与传统的表面活性剂不同，不存在临界胶束浓度，在水中是以&单分子胶束&形式存在。
