A universal amphiphilic block copolymer enables stable, ultrathin monolayer coatings on diverse substrates, including metals, polymers, and nanomaterials. The design combines hydrophilic, hydrophobic, catechol, and crosslinking domains for strong adhesion and antifouling performance.

Innovation Explanation

This invention introduces a multifunctional amphiphilic block copolymer that integrates few domains: a polyglycerol-based backbone with hydrophilic block and hydrophobic block, a catechol anchoring block, and a crosslinking block. This architecture ensures universal adhesion to polar and non-polar surfaces, forming stable monolayer coatings resistant to surfactants and physiological conditions. The catechol groups can be oxidized and crosslinked to secure attachment to polymers and enable covalent stabilization. The coatings exhibit excellent antifouling properties and can be post-functionalized for bioactive applications, making them suitable for both macro-scale and nano-scale interfaces.
