摘　　要：本文以苯乙烯磺酸钠(SS)、7-(4-乙烯基苄氧基)-4-甲基香豆素(VM)和丙烯酸(AA)作为反应单体,合成了一种光敏性双亲共聚物PSVMA,利用1 HNMR与UV-Vis光谱对其结构和组成进行了表征。以PSVMA作为软模板和掺杂剂,氯金酸作为氧化剂,通过化学氧化法聚合得到水分散的PEDOT∶PSVMA/AuNPs导电复合物,平均粒径是66.7±0.5nm。将其作为基础墨水,调节配方制得了PEDOT∶PSVMA/AuNPs喷墨打印墨水,分别以相纸和PET膜为基材制得了图案化的柔性导电膜,该柔性导电膜具有较好的导电性,经紫外光引发导电膜中的香豆素基团二聚后,其耐水性大大提高。In this paper,styrene sulfonate（SS）,7-（4-vinylbenzyloxyl）-4-methylcoumarin（VM）and acrylic acid（AA）were polymerized by free radical copolymerization to form the photosensitive amphiphilic alternating copolymer P（SS-co-VM-co-AA）（PSVMA）.The structure of PSVMA were confirmed by 1 HNMR and UV-Vis spectroscopy.PSVMA was used as the soft template to achieve the oxidative polymerization of poly（3,4-ethylenedioxythiophene）（PEDOT）meanwhile acted as the dopant of PEDOT.Gold precursor chloroauric acid was used as the oxidant for the oxidative polymerization and caused the situ reduction of gold nanoparticles at the same time.The stable PEDOT∶PSVMA/AuNPs photosensitive aqueous dispersion was obtained,and mean diameter was 66.7±0.5nm.PEDOT∶PSVMA/AuNPs aqueous dispersion was used as the base ink to achieve the conductive inkjet printing ink with suitable surface tension and viscosity,obtaining flexible conductive film on photopaper and PET substrates by inkjet printing.Those devices showed good conductivity.At the same time,PEDOT∶PSVMA/AuNPs could be cross-linked after photo-dimerization of coumarin group,which can improve the devices＇ water resistance.
