Coating Compound and Coating Arrangement

Simple SummaryContent extracted from patent full text and abstract with AI.

This invention provides a universal coating compound made from a specially designed block copolymer. The compound includes hydrophilic and hydrophobic domains, catechol domains for strong surface anchoring (especially to metals/oxides), and crosslinking domains that stabilize the coating through intermolecular bonds. This unique composition allows the compound to form thin, stable, monolayer coatings on a wide array of surfaces—ranging from metals and oxides to polymers and nanomaterials—providing antifouling properties and enabling secondary surface functionalization.

BenefitsContent extracted from patent full text and abstract with AI.

• Universal applicability: efficient coating on almost any substrate material (metals, oxides, polymers, glass, graphene, nanoparticles)
• High stability: coatings resist removal by surfactants, sonication, and maintain integrity in physiological conditions over extended periods
• Ultra-thin, monolayer coatings: maintain substrate properties, uniform morphology, and minimal thickness (nanometer scale)
• Antifouling: significantly reduces undesired protein and cell adhesion, outperforming conventional coatings
• Customizable: allows post-fabrication functionalization with various bioactive groups for controlled interactions
• Scalability and robust application: easy coating methods (e.g., dip-coating, sonication) work for both macro and nano-scale objects
• Prevents aggregation of nanomaterials: maintains stable dispersions for nanoparticles and nanosheets
• Biocompatibility: safe for medical and biological uses due to inert, hydrophilic polymer backbones
