NOVELTY - Preparing aminated graphene reinforced waterborne polyurethane comprises (i) mixing isophorone diisocyanate, polytetrahydrofuran diol and 1,4-butanediol and reacting to obtain reaction mixture 1, (ii) adding dimethylolpropionic acid to the reaction mixture 1 and reacting to obtain a reaction mixture 2, (iii) adding triethylamine to the reaction mixture 2 and reacting to obtain a reaction mixture 3, (iv) adding aqueous dispersion of aminated graphene to the reaction mixture 3 to carry out secondary chain extension. USE - The method is useful for preparing aminated graphene reinforced waterborne polyurethane. ADVANTAGE - The polyurethane has good mechanical properties, hydrophobic properties and electrical conductivity.
