제목 Creating Opal Templated Continuous Conducting Polymer Films with Ultralow Percolation Thresholds Using Thermally Stable Nanoparticles
초록 We propose a novel and robust strategy for creating continuous conducting polymer films with ultralow percolation thresholds using polymer-coated gold nanoparticles (Au NPs) and various aspect ratios of CuPt nanorods as surfactants. Continuous poly(triphenylamine) (PTPA) films of high internal phase polymeric emulsions were fabricated using an assembly of crosslinked polystyrene (PS) colloidal particles as template. Polymer-coated NPs were designed to be thermally stable even above 200 ˚C and neutral to both the PS and PTPA phases. Therefore, the NPs localize at the PS/PTPA interface and function as surfactant to efficiently produce a continuous conducting PTPA polymer film with very low percolation thresholds. Morphological studies clearly demonstrated the formation of a continuous PTPA phase within the polyhedral phase of PS colloids.
