Title: POLYURETHANE COMPOSITE
Abstract:
The present invention relates to a thermoplastic polyurethane composite comprising functionalised nanoparticles incorporated into a polyurethane matrix, and to the synthesis method thereof. The method comprises melting a diisocyanate in a reactor in an inert-gas atmosphere, adding a macrodiol until a pre-polymer is obtained, and adding a chain extender. The functionalised nanoparticles can be incorporated into the diisocyanate, the macrodiol or the chain extender.
