Abstract
This article adopts a full life-cycle perspective,systematically reviewing the key characterization technologies involved in each stage of polymer materials,from raw material collection,production and processing,use process to waste disposal.It thoroughly discusses the basis for selecting techniques,such as raw material component analysis,production and processing aid characterization,aging product analysis,microplastic detection,and degradation performance assessment,their working principles,and their specific applications in environmental impact assessment.By systematically reviewing these technologies,their importance in providing comprehensive and scientific evaluation data sources is highlighted,and the core role of these characterization technologies in assessing the environmental impact of polymer materials over their entire life cycle,guiding material selection and formulating environmental policies is further emphasized.In addition,the latest research progress is also introduced,showing how these technologies meet new challenges in current assessments,providing a solid scientific basis for the sustainable development of polymer materials.
