Abstract

Thin layers of, poly-(3, 4-ethylenedioxythiophene) with polystyrene sulfonic acid (PEDOT:PSS) were inkjet printed on polymer films of poly(vinylidene fluoride - trifluoroethylene) (P(VDF-TrFE)). Different ink formulations and the printing parameters were studied in order to optimize PEDOT:PSS layer deposition and the resulting film properties such as the layer homogeneity and conductivity. Printed PEDOT:PSS films were deposited at a temperature of only 30°C, they were partially transparent and they can be deposited with a unique shape or form. Electrical poling and piezoelectric properties of P(VDF-TrFE) layer with inkjet printed PEDOT:PSS electrodes were investigated. It was determined that layers printed from PEDOT:PSS inks with special surfactants and additives are suitable electrodes for ferroelectric polymers and piezoelectric transducers.
