    Dow Corning polydimethylsiloxane pdms base resin
    Formation and the characterizations of the chain entanglement-mediated zwitterionic physical hydrogel coatings. a) Schematic illustration of the formation of the chain-entangled hydrogel coating. b) Representative SEM images of the substrate <t>PDMS</t> and coatings prepared at different monomer concentrations. c) Molecular weights of the dissolved polymer coating. Coated samples undergo substrate degradation, dialysis, lyophilization, and GPC testing. d) Statistical thickness data of the coatings in dry and swollen states prepared at different monomer concentrations ( n = 3), where a polymer brush's theoretical swollen thickness limit is calculated based on the molecular weights, assuming the polymer chains are fully extended. e) Schematic illustration of the coating structure prepared at different monomer concentrations.
