A simple device for dielectric spectroscopy of polymers with temperature regulation close to 300 K based on a Peltier junction
Abstract
We present a simple thermostat device for performing dielectric spectroscopy measurements on polymers
close to their glass transition temperature. By using a vacuum chamber containing a Peltier
junction with its regulator, we show that a very simple setup yields a temperature accuracy which
is good enough for accurate studies of polymer dielectric properties. This technique is also more
cost effective than standard setups using cryogenic fluids
