Abstract

In the present work, the effect of temperature and moisture has been studied on nano-porous polycarbonate membranes of size 15, 50, and 80 nm, respectively to formulate the calibration curves for the future development of humidity sensors. These studies were conducted for virgin as well as humid samples while the temperature range was kept from room temperature to 160°C. Interesting variations in the capacitance with pore size and temperature have been observed. Calibration curves demonstrate that nanoporous polycarbonate samples are one of the important candidates for developing humidity sensors. In addition surface behavior has also been studied for the selective samples to better understand the dielectric behavior for nascent as well as moisturized samples.
