Pdms-Based Barium Titanate Piezoelectrical Coatings for Antifouling

This study aims to exploit a piezoelectric composite based on polydimethylsiloxane (PDMS) and barium titanate (BTO) and apply it to antifouling coatings for electrical equipment. BTO nanoparticles and nanorods (BTO NPs and NRs) were synthesized using the hydrothermal method and were characterized by SEM, TEM, XRD, and FITR tests. The prepared nanomaterials were composited with a PDMS matrix to prepare piezoelectric composites with different mass fractions. The piezoelectric property tests showed that the <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$5 \text{wt} \%$</tex> BTO NPs/PDMS composite exhibited the highest piezoelectric coefficient <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$d_{33}$</tex> and the best piezoelectric output in its PENG. Importantly, the BTO/PDMS coated insulators can effectively reduce the adhesion of dirt under the DC field, which provides a new idea for the design of new environmentally friendly anti-fouling materials for power transmission systems.
