A Novel Amphiphilic Siloxane-Polyurethane Fouling-Release Coating
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...
