【综合报道】12月8日消息,据外媒报道,阿克伦大学的科学家们近日研发出了一种新型聚乳酸(PLA)塑料,这种塑料可用来盛装沸腾的液体。据了解,虽然和传统那些用原油和天然气制造的塑料相比,生物塑料有很多环境效益,但后者往往也会在一些关键领域表现欠佳

【综合报道】12月8日消息,据外媒报道,阿克伦大学的科学家们近日研发出了一种新型乳酸(PLA)塑料,这种塑料可用来盛装沸腾液体

据了解,虽然和传统那些用原油和天然气制造的塑料相比,生物塑料有很多环境效益,但后者往往也会在一些关键领域表现欠佳。

比如,作为一种常见的生物塑料,传统的聚乳酸材料生产成本较低,常被用来制成食品包装、塑料瓶和餐具等物品。不过,该种材料不适宜存放高温物体,因为其在一定温度下会发生结构性塌陷。

基于此,在王世庆(音译)博士的带领下,阿克伦大学的科研团队聚焦聚乳酸塑料的复杂结构,通过调整晶体的形成方式最终研发出了新型聚乳酸塑料。

该团队表示:“用这种新型材料制成的杯子可以盛装沸腾的液体,且不会收缩和降解。未来,这种杯子有望成为盛装热茶和咖啡的更环保的选择。”

据悉,目前该研究成果已发表在期刊Macromolecules上。
