Plastics are used in many fields due to its ease of processing and excellent durability. However, compared to the large amount of use, disposal method is a problem that has not been solved yet. In particular, thermosets with excellent thermal and chemical stability cannot be degraded, so most of them are treated by landfilling. To solve this problem, researches on the degradation of thermosets through dynamic covalent bonds have conducted, but there is a limitation that requires a lot of energy. Therefore, in this study, degradation rate is accelerated by improving thermal conductivity through the introduction of graphene oxide and the possibility of recycling the graphene oxide is confirmed.
