Thermoelectric properties of metashale geopolymer with graphite powder in the dry and wet state

Original language description

The design process of new civil engineering materials (composites) is increasingly focused on two important targets. It is the utilization of alternative cementless binders meeting the circular economy concept and optimization of properties ensuring favorable additional material functions for civil engineering applications. Optimization of thermoelectric properties is an important issue within the design of building materials with energy harvesting potential (conversion of heat to electrical energy) and evaluation of thermoelectric conversion efficiency is crucially dependent on the Seebeck coefficient, electrical conductivity and thermal conductivity parameters. The paper is focused on material characterization of the designed metashale geopolymer with 3 wt. % of graphite powder (GP) by means of basic physical, mechanical, thermal, electrical, and thermoelectric properties. The Seebeck coefficient determined in dry- and wet state were of -27.57 􀁐V􀃂K-1 and -69.78 􀁐V􀃂K-1, respectively. 2.23x10-6. The thermoelectric conversion efficiency indicators represented by the power factor (PF) and the figure of merit (ZT) exhibited a significant increase caused by water presence (PFdry = 1.7x10-15 W􀃂m-1􀃂K-2, ZTdry = 5.9x10-13, PFwet = 9.6x10-11 W􀃂m-1􀃂K-2, ZTwet = 2.6x10-8).
