  • Facile clay exfoliation using polymer silicone surfactants
    Patent number: 10981830
    Abstract: The present invention is directed to processes for preparing a silicone surfactant intercalated clay and a polymer-clay nanocomposite. The processes use silicone surfactants having a molecular weight in the range of 10,000 to 100,000 Dalton to achieve fully exfoliating clay structures. Using these macromolecular silicone surfactants, along with the engineered control of the processing pH and drying stress conditions, this invention provides simple and low-cost methods of making a fully-exfoliated polymer-clay nanocomposite.
    Type: Grant
    Filed: July 22, 2019
    Date of Patent: April 20, 2021
    Assignee: Industrial Science & Technology Network, Inc.

  • Polymer blend nanocomposites using nanocompatibilizer and method of manufacture thereof
    Patent number: 8067489
    Abstract: The invention for the nanocompatibilizer composed of a nanoclay and a compatibilizer prepared through a melt blending process is disclosed. The enhanced mechanical properties stemming from the increased compatibility for metallocene polyethylene/starch blends are attained with the addition of the nanocompatibilizer, in comparison with neat compatibilizer, which signified the role of nanocompatibilizer in the derived nanocomposites.
