| 摘 要： | 静电自组装是指将带相反电荷的聚电解质，于水溶液中交替沉积在片基上，制备多层超薄膜的技术．由于它在水溶液进行，技术简单，无需专用设备，再加上静电力比范德华力强，因此静电自组装膜比传统的LB(Langmuir—Blodget)膜稳定，在近年来得到很大发展．现在自组装成膜驱动力已从最初的静电力扩展到氢键、电荷转移相互作用、疏水相互作用等；用于组装的组分也从聚电解质扩展到多官能团小分子、胶体粒子、无机纳米

| Abstract: | Poly(4-diazosulfonate styrene-co-4-vinylpyridine) (P(DSS-co-VP)),containing both H-acceptor moieties of pyridine and photosensitive diazosulfonate groups,was synthesized and has been used for self-assembly as a new component.The layer-by-layer deposition between P(DSS-co-VP)and m-methyl phenol formaldehyde resin (MPR) on a substrate via H-bonding interaction was investigated.After UV irradiation the stability of the multiplayer ultra thin film toward polar solvents is improved dramatically.The improvement of the solvent stability of the film should be attributed to the bond conversion between the layers of the film from H-bond to covalent bond under UV irradiation. |
