Surface Chemistry in Environmental Degradation of Polymeric Solids
Summary
Researchers reviewed the three main degradation pathways of plastic materials from a surface chemistry perspective: chemical, biological, and mechanical degradation. They described how these processes can occur consecutively or simultaneously in the environment, ultimately producing microplastics. The study provides a scientific framework for understanding how plastics break down into smaller particles, which is essential for developing strategies to address microplastic pollution.
Microplastics (MPs) cause significant adverse environmental effects. To address this issue, a scientific approach for understanding the formation of MPs is essential. In this Perspective, we summarize the three typical degradation behaviors of polymeric solids from a surface chemistry perspective: chemical degradation, biodegradation, and mechanical degradation. These three degradation processes can occur consecutively or simultaneously in poorly managed polymeric materials, ultimately resulting in their disintegration into the environment. This Perspective provides valuable insights into controlling the degradation of polymeric solids and designing eco-friendly polymers for a sustainable future.
