Chinese scientists have developed a plastic that degrades in seawater and could help curb the increasingly serious plastic pollution in the oceans. 我国科学家近日研制出一种可在海水中降解的塑料，或将有助于控制日益严重的海洋塑料污染问题。 The new polyester composite material can decompose in seawater over a period ranging from a few days to several hundred days, leaving small molecules that cause no pollution, said Wang Gexia, a senior engineer at the Technical Institute of Physics and Chemistry of the Chinese Academy of Sciences. 中国科学院理化技术研究所高级工程师王格侠介绍，这种新型的聚酯复合材料可在数天到数百天内在海中降解，最终分解为不会对环境造成污染的小分子。 |
