The study of methods to enhance the properties of composite materials for various application areas is an enduring topic. In this paper. a high-performance filler was prepared by grafting hexamethylene diisocyanate (HDI) and amino-terminated butadiene nitrile rubber (ATBN) onto graphene oxide (GO). Epoxy resin (EP) was selected as the object of feasibility verification. https://goodvibesbadhabiters.shop/product-category/nextgen-dolls/
