  • Antimicrobial Polymer Nanocomposites
    Publication number: 20100216908
    Abstract: A method of preparing a polymer nanocomposite having antimicrobial properties, comprises (i) contacting a polymeric antimicrobial agent with a clay to form an organoclay; and (ii) subsequently dispersing the organoclay in a polymeric matrix. Polymer nanocomposites prepared by the method of the invention are not prone to leaching of the polymeric antimicrobial agent from the composite, and have many applications.

  • Nanocomposites
    Patent number: 6835766
    Abstract: Polymer-clay nanocomposites are formed by compression of an intimate mixture of the polymer and the clay. The compression is carried out below the glass transition temperature for amorphous polymers or between glass transition temperature and melting point for crystalline polymers, and preferably at ambient temperature.
