Block Copolymer and Fluorinated Electroactive Polymer Resins for Surface Patterning and Printed Electroactive Devices
Abstract :
We present recent advancements in the application of functional polymer resins deposited via wet deposition techniques, focusing on their use in nano-manufacturing and organic electronics. This work includes two case studies.
First, we introduce an elegant method for generating periodic surface patterns using nanostructured block copolymer layers. These patterns, with periodicities ranging from a few nanometers to hundreds of nanometers, hold promise for next-generation nanofabrication, particularly in lithography. While the geometric features of block copolymer architectures impose certain limitations, we propose novel strategies to diversify these structures through precise interface manipulations and iterative deposition processes.
Secondly, we overview the fabrication and functional characterization of printed organic devices based on fluorinated electroactive polymers for applications in environmental monitoring and energy conversion. In particular, we examine the use of P(VDF-TrFe) for the fabrication of pyroelectric sensors by screen printing and evaluate the pyroelectric performance of the printed thermal detectors.
