Lu HE, Jia-bin SHEN, Shao-yun GUO. Research Progress in Modification of Waste Plastics[J]. Polymer Bulletin, 2021,34(2):18-28. DOI: 10.14028/j.cnki.1003-3726.2021.02.003.
Plastic products have become the major commodities on a global scale and have infiltrated almost every aspect of human life. Meanwhile
the rapidly accumulated waste plastics have caused a series of negative impacts on the terrestrial and ocean environment. Noticeably
waste plastic has the dual characteristics of resources and waste. The improvement of recycling quality and quantity of waste plastics is of great significance to the efficient utilization of resources
sustainable development and environmental protection. Besides
the Herein
the sorting methods commonly used for waste plastics were introduced
the research progress of chemical (such as chain extension
grafting and crosslinking reaction) and physical modification (such as of waste plastics were reviewed
and the problems of the reuse of waste plastics were also analyzed.
