Properties
Description
This hybrid material features crystalline silver nanoparticles encapsulated within a copolymer shell of poly(carboxybetaine-co-dopamine) (PCBDA). The dopamine segments form a robust, coordinate-bound anchor layer directly over the silver facets, while the zwitterionic carboxybetaine segments extend outward to form a neutral, heavily hydrated hydration brush layer. This structural configuration completely eliminates non-specific macromolecular fouling and guarantees long-term colloidal suspension across wide ranges of fluid salinity or temperature.
