Since their discovery, polymers have increasingly replaced other materials (metal, glass, wood, etc.) because of their low cost and their relatively easy shaping. In order to study the stability of a polymer to electron beam irradiation, we chose to use a known method for the study of electron-matter interaction and we applied it to evaluate the damage performed that is known as Monte Carlo simulation by the CASINO program. The results of the simulation allowed us to define the electron-polymer interaction volume and the depth profile of the electrons as a function of their initial energy (5 keV), which allowed us to assess the volume susceptible to damage by the electrons. We were also able to determine the minimum grain sizes of the charges to be added as a function of the incident energy (1, 3, 5, 10, 20 keV) to improve the stability of the polymer.
