A method of fabricating highly transparent and conductive interpenetrated carbon nanotube-parylene networks

摘要

We report a method of fabrication of free standing and ultra-thin carbon nanotube-parylene-C interpenetrating networks. The network is highly transparent, highly flexible, and more conductive than transparent nanotube/polymer composites. Scanning electron microscope imaging reveals that the interpenetrated networks are dense and pinhole free compared to bare nanotube networks. We found that parylene-C coats along carbon nanotubes and links them together, increasing both the mechanical robustness of the film, and the electrical stability under UV radiation. This method is universal for fabricating interpenetrating networks of other nanoscale materials such as nanowires and nanofibers.
