Title: Xuejun Cui and the Recycling of Waste Polystyrene
Introduction
Xuejun Cui is an inventor associated with Jilin University in Changchun City, China. His patent work addresses the recycling of waste polystyrene through a process that uses heated water to promote swelling and depolymerization.
Latest Patents
Cui is associated with 1 patent, titled “Recycling Method of Waste Polystyrene.” The method subjects waste polystyrene to an initial swelling and dissolving process in water heated to 140°C–300°C. At these temperatures, the material may swell and depolymerize, while its polymer chains may also stretch and break down. The patent describes these effects as a dual depolymerization mechanism that remodels the polystyrene.
Career Highlights
Cui’s listed patent work connects his inventive activity with Jilin University. The recycling method focuses on processing discarded polystyrene through heat-driven changes in water.
Collaborations
Cui’s named coworkers include Yan Gao and Jialin Guo.
Conclusion
Xuejun Cui’s patent presents a water-based approach to waste polystyrene recycling, using high temperatures and depolymerization to remodel the material.
