- Abstract
- Polymer layered-silicate (PLS) nanocomposites are materials with unique properties when compared to conventional filled polymers. For example, the mechanical properties of nylon-6 layered-silicate nanocomposite, with silicate mass fraction of only 5%, show excellent improvement over those for the pure nylon-6. The nanocomposite exhibits a 40% higher tensile strength, 68% greater tensile modulus, 60% higher flexural strength, and a 126% increased flexural modulus. The heat distortion temperature (HDT) is increased from 65 deg C to 152 deg C. Previously, we reported on the flammability properties of delaminated nylon-6 layered silicate nanocomposites and intercalated polymer layered-silicate nanocomposites prepared from polystyrene, PS, and polypropylene-graft-maleic anhydride, PP-g-MA. Here, we will briefly review these results and report on our initial studies of the flammability of thermoset PLS nanocomposites: intercalated vinyl ester silicate and intercalated epoxy silicate nanocomposites.
