Abstract:
Micro-contact printing (µCP) is a soft lithography process that offers an alternative route for the formation of conducting polymer structures on a variety of substrates for application in polymer-based sensor and electronic devices. The present study is focused on creating polypyrrolebased sensor structures on a flexible, bio-compatible substrate (poly(tetrafluoroethylene), PTFE). The key requirements are to optimize polypyrrole (PPy) growth on an active metal (copper), to form an adherent multi-layer film with appropriate interlayer grafting that incorporates PPy and copper layers, and to pattern this structure using µCP to create sensor arrays.
