Research and Application of Polypropylene Carbonate Composite Materials: A Review

The greenhouse effect and plastic pollution caused by the accumulation of plastics have led to a global concern for environmental protection, as well as the development and application of biodegradable materials. Polypropylene carbonate (PPC) is a biodegradable polymer with the function of carbon sequestration, which has the potential to mitigate the greenhouse effect and the plastic crisis. It has the advantages of good ductility, oxygen barrier and biocompatibility. However, the mechanical and thermal properties of PPC are poor, especially the low thermal degradation temperature, which limits its industrial use. In order to overcome this problem, PPC can be modified using environmentally friendly materials, which can also reduce the cost of PPC-based products to a certain extent and enhance their competitiveness in terms of improving their mechanical and thermal properties. In this paper, we present different perspectives on the synthesis, properties, degradation, modification and post-modification applications of PPC. The modification part mainly introduces the influence of inorganic materials, natural polymer materials and degradable polymers on the performance of PPC. It is hoped that this work will serve as a reference for the early promotion of PPC.

Automated summary

This paper discusses the synthesis, properties, degradation, modification, and post-modification applications of polypropylene carbonate (PPC), a biodegradable polymer with carbon sequestration function. The disadvantages of PPC, such as poor mechanical and thermal properties, are also addressed. Environmentally friendly materials can be used to modify PPC and enhance its performance. The influences of inorganic materials, natural polymer materials, and degradable polymers on PPC properties are presented. This research provides valuable reference for the early promotion of PPC.
