Petroleum-based plastics have been widely used due to their ease of use and their proven strength and lightweight properties. However, concerns about resource depletion and non-degrading properties of petroleum plastics always threaten the global environment. Poly(butylene succinate) (PBS) is one of the biodegradable aliphatic polyesters that can be degraded by microorganisms. In this study, the addition of surfactants and UV irradiation conditions set as conditions for accelerating the degradation of PBS, and the biodegradation behavior was investigated. For the physicochemical characterization of PBS according to the biodegradation behavior, FE-SEM, FT-IR, GPC analysis and tensile experiments were performed. As a result, both the surfactant and the UV irradiation environment accelerated the biodegradation of PBS. In particular, the surfactant has a considerable impact on the reduction of molecular weight and the UV irradiation on the decrease of mechanical properties. |
