提出在玻璃基体表面原位聚合沉积制备苯胺-邻苯二胺(An-oPD)共聚物薄膜的一种方法:分段控温法,即高温预聚(高水浴温度)、低温聚合(冰水浴)。该法可在缩短聚合反应时间的同时避免暴聚现象,提高成膜效率,所得共聚物薄膜形貌特征优异、膜厚均匀;该法可制得饱和厚度120 nm,电导率9.16×10-2S/cm的An-oPD共聚物薄膜,具有与均聚PAn薄膜不同的电致变色性能。
Step thermoregulation was raised that in-situ polymerization deposition of aniline/o-phenylenediamine(An-oPD) copolymer film on the surface of glass substrate,high temperature pre-polymerization(hot water bath), low temperature polymerization(ice water bath).It can reduce the polymerization time,avoid the phenomenon of violent polymerization,improve the polymerization efficiency and prepare high quality hydrochloric acid-doped An-oPD copolymer film of excellent morphology and thickness uniformity.Applying this method,An-oPD copolymer films can be available with thickness of 120 nm,conductivity of 9.16 ×10~(-2) S/cm,electrochromic properties of copolymer films are different from the homopolymerization PAn films.
