摘要
采用分子动力学法研究了自组装单分子膜粘结剂(SAMY和SAMN)对铜/环氧树脂界面相互作用能的改造,并考虑环氧树脂交联程度、环境温度和吸湿量的影响。结果表明,与环氧树脂形成化学键的自组装单分子膜SAMY能够加强铜与环氧树脂间的粘结作用,而不与环氧树脂形成化学键的SAMN则减弱了铜与环氧树脂间的粘结作用;同时,温度升高、含湿量增加均会导致界面粘结强度降低;交联度增大,使含SAMY的界面相互作用能降低,而含SAMN的界面相互作用能几乎不受影响。
Two kinds of self-assembly monolayers(SAMs),SAMY and SAMN,were added to Cu-epoxy interface and the effects of temperature,moisture and crosslink conversion on the modified interfaces were investigated with molecular dynamics(MD)simulation.Covalent bonds between SAMY and epoxy enhance the interfacial adhesion of Cu-epoxy.However,the non-bond interactions of SAMN and epoxy resin weaken the interfacial adhesion.In addition,the results show that high temperature and high moisture content will weaken the interfacial adhesion.And the interfacial interaction energy of the systems with SAMY increases with the decreasing crosslink conversion,while that of the systems containing SAMN is reluctant to the crosslink conversion.
