DESCRIPTION
This technology describes a curable polyurethane coating that integrates both hydrophobic and hydrophilic components, polydimethylsiloxane (PDMS) and poly(ethylene glycol) methyl ether (mPEG), to create an amphiphilic surface that resists biofouling. When cured, the coating self-stratifies, forming a surface layer that minimizes adhesion of marine organisms such as algae, bacteria, and mussels while maintaining mechanical durability and strong adhesion to substrates. The formulation achieves a balance between flexibility, toughness, and low surface energy, offering a non-toxic, biocide-free alternative to traditional antifouling paints for marine and industrial surfaces exposed to aquatic environments.
