  • System and method for synthesis of POSS-starch derivatives as effective fillers for developing high performance composites
    Patent number: 10155851
    Abstract: According to an embodiment, natural polymers will be used to enhance the biodegradability of nanocomposites, increase potential use of sustainable polymer matrices, improve the interlaminar fracture toughness of graphite/epoxy composites and attain complete nanoparticle dispersion through covalent bonding of nanoparticles and natural polymers. The starch derivatives containing POSS (polyhedral silsesquioxane) were synthesized by reacting natural polymer with different POSS molecules in a solvent in presence of a catalyst. Interlaminar fracture toughness testing results from the epoxy based nanocomposites containing 3, 5, 7, and 10 wt % POSS modified natural polymer in the interlaminar area are presented. The biodegradability of the composites is expected to improve through the incorporation of the natural polymer derivatives.
