Investigating Piezoresisitive and Thermopresisitive Response for the Multifunctionalization of Bio-Epoxy/Carbon-Based Nanofiller Composites

DATASET. This research focuses on developing bio-based electrically conductive polymer composites for multifunctional applications like coatings, adhesives, and sealants. Using Epoxidized Soybean Oil (ESO) and Tannic Acid (TA) as a bio-epoxy matrix, multi-walled carbon nanotubes (MWCNTs) and reduced graphene oxide (rGO) were added to impart electrical conductivity. These composites exhibited piezoresistive and thermoresistive properties, making them suitable for sensing applications. Evaluations showed good mechanical properties, hydrophobicity, and stable functional responses under low stress and temperatures up to 80°C. Their electrical conductivity and sensitivity confirm their potential for advanced applications, including protective coatings in offshore wind energy industries.
