Abstract

Electroactive polymers have gained significant interest in fields such as the development of artificial muscles, control systems, medical devices, and more. Additionally, carbon nanotubes (CNT) are an excellent option for these purposes because they possess outstanding mechanical and electrical properties, which can enhance the rigidity and electrical conductivity of polymers. However, despite extensive studies on CNT, very few of them have addressed the deformation of polymeric matrices caused by the orientation of CNT under the influence of an electric field. Therefore, this work presents a preliminary approach to the deformation of a polyethylene matrix with CNT inclusions. To achieve this deformation, the orientation of the CNT was simulated using the finite element method, where an electric field was generated by applying a potential difference of 10 volts (ranging from -5 to 5 volts across two conductors), resulting in an electric field . The electric field, in turn, induces a moment and polarization on the nanotubes, causing them to align vertically. The results showed that the polyethylene matrix exhibited the highest deformation in regions with CNT inclusions, while the highest stress concentrations occurred within the nanotubes themselves.
