| Three different methods of surface modification using polymers on hydrophilic particulates are compared. Effective surface modification with a polymeric coating is achieved by in-situ graft polymerization; grafting of preformed polymers; and admicellar polymerization which uses a surfactant template. Sample characterization includes Raman spectroscopy, gravimetric analysis, contact angle measurements and capillary rise measurements. In all cases, the presence of polymer on the surface was confirmed, but differences in terms of amount of polymer adsorbed and surface chemistry of the modified samples were found. Those differences are highlighted in this poster. |
