Anti-fouling coatings are increasingly the focus of research, especially when they do not require biocidal additives. A Chinese research team has now developed novel amphiphilic acrylate copolymers that contain zwitterions and thus offer a promising approach for biocide-free biofouling prevention in marine applications. Fine-tuning the hydrophilic TMS and hydrophobic LMA content was crucial for the performance of the coating.
