Enhancing The Thermoelectric Properties Of Polymers Base Composites

Abstract

Thermoelectric polymers are a very promising class of thermoelectric materials, is widely used for number of temperature sensitive applications in various industries and clinical laboratories. These are the polymers that have the specific characteristics for the conversion of waste heat into electric energy, however; low conversion efficiency of such polymeric material is the major drawback for such materials.
Polymer base work is focused on studying their improvement in the figure of merit of UHMWPE by adding 10000ppm, 50000ppm, 70000ppm, 100000ppm, 150000ppm, and 200000ppm loadings of grapheme-oxide. The presence of GO and structural stability has been performed while using XRD analysis. For thermoelectric purpose figure of merit has been calculated by using the data of electrical conductivities, Seeback coefficients and thermal conductivities for each formulation. It was found that the value of the figure of merit is 9.97×10-11 for 200000ppm loading, which the highest among the all under investigation.
