The study of polymers based on the biomass has become an area in continuous growing due to their potential uses in diverse fields and the ecological advantages in comparison to petroleum based materials. Tung oil is a highly unsaturated oil extracted from the seeds of the tung tree that can be reacted with a vinyl monomer like styrene in the presence of a cationic initiator1. Previous works have showed that some compositions exhibit shape memory properties1. The addition of magnetic iron oxides to these formulations can expand their uses. The magnetic nanoparticles of iron oxides (MNP) can absorb electromagnetic energy from an external high-frequency field and release it as heat, which under specific conditions, can be used to trigger the shape memory response of the nanocomposites2. This work presents the study the magnetohyperthermia effect as a function of the MNP content on a polymer based on tung oil and styrene.
