Synthesis, characterization and performance evaluation of epoxy/pedot: Pss-cerium doped zinc oxide as anticorrosive and hygienic hybrid composite

Many high-end industries including the marine, oil and gas, and biomedical industries are severely affected by metal corrosion and the presence of microbial activity further accelerates the corrosion process. The smart functional coating materials with synergistic anticorrosion and antifouling pr...
