摘要： The method of manufacturing polyurethane elastomer nanocomposites with the use of oligomerols, oligoesterols and/or oligoetherols, diisocyanates, chain extending or cross-linking agents, amine or organometallic catalysts, and graphene oxide or its reduced form wherein the prepolymer containing 4-20% of free isocyanate groups NCO originated from oligomers in the form of oligoetherols and/or oligoestrols with a molecular weight between 400 and 15 000 g/mol is mixed with 0.01-10 wt.% of nanofiller in the form of graphene oxide, its reduced form, or the nanofiller dispersion prepared in polar or nonpolar solvent, in oligomeric component or in the oligomerol-based mixture containing low-molecular-weight chain extender, or dispersed in isocyanate agent. Next, the mixture is intensively homogenized at a temperature between 10 and 60°C and the stirring rate up to 10000 rpm for 3 hrs in an ultrasound bath.
