Abstract: Methods of making bearings using pressure sensitive macromolecular adhesive polymers and pressure sensitive polymer compositions capable of integrating fluoropolymeric properties with a catechol-amine functionality to form an adhesive system that allows bonding between metallic substrates and fluoropolymers are disclosed. Also disclosed are core-shell polymeric particles comprised of a core and a shell comprising a thermoplastic polydopamine polymer that may be prepared as a colloidal suspension and used as a hot-melt pressure sensitive adhesive capable of binding low surface energy materials, such as polyolefins and fluoropolymers, to diverse materials including metals in making bearings and/or bearing components.
