Surface Graft Copolymerization of Conducting Polyaniline on Waterborne Polyurethane-urea(WBPU) Films-The Effects of the Reaction Condition /Ionic Content on the Grafting, Conductivity, and their Sensor Performance for Phenol |
초록 |
A sesies of waterborne polyurethane (WBPU) containing various dimethylol propionic acid (DMPA) contents (14, 19, 24 mol%) were prepared. The WBPU-grafted-polyaniline composites films were successfully prepared by oxidative polymerization of aniline on the surface layer of WBPU films in the presence of oxidant ammonium persulfate (APS). The relationships between grft percentage and experimental conditions, such as the concentrations of aniline and APS, reaction temperature and time were extensively investigated. The effect of DMPA content on the graft percentage and conductivity was also studied. In addition, the polyaniline-grafted WBPU films on exposure to 1000ppm~1ppm aqueous phenol show a well-defined response behavior and this aspect has been utilized in designing the Phenol sensor. |
