Abstract

Se divulga una dispersión de nanopartículas de carbono de grafeno que comprende un solvente, mayor que uno por ciento en peso de nanopartículas de carbono de grafeno basado en un peso total de la dispersión que comprende nanopartículas de carbono de grafeno producidas térmicamente y partículas de grafeno base, y un dispersante de resina polimérica; la relación en peso de las nanopartículas de carbono de grafeno al dispersante puede ser mayor que 5:1, y la dispersión puede tener un índice de inestabilidad menor a 0,7; también se divulga un método para dispersar partículas de carbono de grafeno en un solvente; un dispersante de resina polimérica es mezclado en el solvente, y las nanopartículas de carbono de grafeno que comprenden nanopartículas de carbono de grafeno producidas térmicamente y partículas de grafeno base son dispersadas en el solvente.
