We report fabrication exfoliation of montmorillonite (MMT) using 2-chloro-3’, 4’-dihydroxyacetophenone (CCDP) and 1,3-propanesultone quaternized poly(dimethyl amino)ethyl methacrylate [(C/S)-q-PDMA]. The catechol in this platform allowed easy access to surface coatings to incorporate an antifouling capability, confirmed by contact angle, XPS measurements and HeLa cell detachment. To more advance this system, we are incorporated active near-infrared (NIR) tungsten oxide (WO3) and iron oxide (Fe3O4) in MMT followed by appropriate material characterization. Metal oxides-immobilized MMT showed colloidal stability and photothermal effect, due to magnetic Fe3O4, the nanocomposites showed reusable behavior for killing both strains bacteria within 4 min of NIR irradiation. Finally, this approaching is promising coating composite for antifouling material and effective and stable composite for killing bacteria. This study was supported by Korea National University of Transportation at 2016. |
