1. A process for incorporating carbon nanomaterials into a polymeric matrix, comprising:
a. producing reduced graphene oxide (RGO);
b. sieving the RGO obtained in step “a”;
c. incorporating the RGO produced in step “a” into a fusion-bonded epoxy polymer matrix (FBE) in powder form, with a ratio of 1 g/kg to 10 g/kg of RGO in relation to the FBE, using a planetary ball mill or high energy planetary ball mill, for a period of time of 1 to 10 minutes, with speed between 200 and 2000 rpm.
