摘要

塑料垃圾对环境、人类健康和生态系统的影响是当今最重要的问题之一。一旦释放到环境中，塑料垃圾就会暴露在各种应力因素中，这些应力因素可能导致其结构完整性降低，从而导致其碎片变小。本工作研究了模拟紫外线老化对高密度聚乙烯（HDPE）薄膜表面性能和断裂的影响。用原始聚合物颗粒制备HDPE薄膜

From Macro to Micro Plastics; Influence of Photo-oxidative Degradation

The impact of plastic waste on the environment, human health, and ecosystems is one of the most important issues today. Once released into the environment, plastic waste is exposed to various stress factors that can lead to a reduction in its structural integrity and consequently to its fragmentation into smaller pieces. In this work, the effects of simulated UV aging on the surface properties and fragmentation of high-density polyethylene (HDPE) films were studied. HDPE films were prepared from pristine polymer granules
