Investigation of the properties of electrically conductive interpenetrating polymer networks for the use as temperature sensors

Abstract

We report on our newest studies of electrically conductive interpenetrating polymer networks (IPNs) for application in temperature micro sensors. We manufactured polymeric structures on glass with a micro pattern generator by exposing a combination of Novolak and Terthiophene doped with copper(II) perchlorate with a UV laser. We assessed the effects of prolonged temperature loads on the structures’ impedances in a range of 30 to 130 °C. Such polymers and our approach may be of interest for the fabrication of different micro sensors, particularly when only a limited number of highly specialized sensors is required, e.g. for fire safety infrastructure.

An electrochemical quartz crystal microbalance (EQCM) based on microelectrode arrays allows to distinguish between adsorption and electrodeposition

“…The procedures were in part dictated by the instrumentation available to us. 47 Structuring occurred with a micro pattern generator (a laser lithograph, the unit µPG101 from Heidelberg Instruments, Heidelberg, Germany, λ = 375 nm). The laser lithograph avoids a mask, which is convenient (Fig.…”
