Antimicrobial enhancement via Cerium (II)/Lanthanum (III)‐doped TiO2 for emergency leak sealing polyurea coating system

Abstract Industrial piping structures often suffer from corrosion caused by biofouling or chemical etching, which can cause immediate structural failure. Polyurea coatings, are fabricated for emergency leak sealing, able to form high mechanical strength coating surfaces within seconds. After its further modification via Ce/La-doped TiO 2 , the polyurea will indicate an increment in strength, durability, and reduction of microbial attachment. Due adsorption generation reactive oxygen species (ROS), E. coli Pseudomonas may lose their living conditions during progress, planktonic bacteria cells prevented enriching on surface. The Ce/La‐dopants also improve original photocatalytic response nano-TiO UV light environmental temperature. These coatings illustrate application sealing purposes without any production interruption it prolong time intervals maintenance service as well.
