▎ 摘　　要

NOVELTY - A polyurethane elastomer nanocomposite is obtained from oligoetherol and/or oligoestrol having molecular weight of 400-10000 g/mol and hydroxyl number of 10-100 mg potassium hydroxide/g, diisocyanate having oligomerol ratio of 2-15:1, diol or diamine chain extender having low molecular weight, or triol or triamine crosslinking agent with final isocyanate/hydroxyl ratio of 0.9-1.15, 0.01-10 pts. wt. amine or organometallic catalyst, and 0.01-10 pts. wt. nanofiller. The nanofiller is graphene oxide, reduced graphene oxide or dispersion of graphene nanofiller in polar or non-polar solvent. USE - Polyurethane elastomer nanocomposite (claimed). ADVANTAGE - The polyurethane elastomer nanocomposite has high Youngs modulus, stress resistance, elongation at break, elasticity, water-barrier capacity, optical transparency, electrical conductivity, flame resistance, thermal resistance and thermal stability. DETAILED DESCRIPTION - A polyurethane elastomer nanocomposite is obtained from oligoetherol and/or oligoestrol having molecular weight of 400-10000 g/mol, hydroxyl number of 10-100 mg potassium hydroxide/g, and functionality of 2, diisocyanate having oligomerol ratio of 2-15:1, diol or diamine chain extender having low molecular weight, or triol or triamine crosslinking agent with final isocyanate/hydroxyl ratio of 0.9-1.15, 0.01-10 pts. wt. amine or organometallic catalyst, and 0.01-10 pts. wt. nanofiller. The nanofiller is graphene oxide, reduced graphene oxide or dispersion of graphene nanofiller in polar or non-polar solvent. An INDEPENDENT CLAIM is included for manufacture of polyurethane elastomer nanocomposites.
