PEDOT: PSS-Enabled CNT and Bi_0.5Sb_1.5Te₃ Interface Microengineering for Integrated Thermoelectric Energy Harvesting and Corrosion Protection in Cementitious Composite.

ABSTRACT: Thermoelectric cement-based composites integrate thermoelectric effects with structural capabilities, presenting an effective solution for harvesting environmental heat in self-powered cathodic protection. While the prospects are promising, their performance has been constrained by the compatibility between functional fillers and cementitious materials. This study demonstrates that PEDOT: PSS(PP) significantly improves the dispersion of multi-walled carbon nanotube (CNT) and Bi_0.5Sb_1.5Te₃ (BST) in cementitious materials. The optimized composite(0.2 wt.% CNT, 1.0 vol% PP, and 1.0 wt.% BST) exhibits a 28.4% increase in conductivity and a 15.9% reduction in thermal conductivity compared to the control. Additionally, it achieves an impressive Seebeck coefficien
