匹兹堡大学研发疏水性优异的光学塑料
University of Pittsburgh developed excellent hydrophobic optical plastics

据 cnBeta 消息，匹兹堡大学副教授 Paul Leu 领导的一组研究人员研制了一种疏水性优异的光学塑料，该材
料的表面沉积了一层紧密间隔的高而薄的纳米结构，顶部则有圆形斑点，这一构造与金针菇十分的相似。
据了解，Paul Leu 教授研发这种材料时，也是受到了金针菇结构的启发，并采用了苯二甲酸乙二醇酯 (PET)
的形式。这种塑料被称作为 enoki PET，颜色是透明的，无论是水、牛奶、番茄酱，咖啡还是橄榄油等其他液体，
都可以从其表面滑落。
即使经过 5 000 次弯曲循环，这些组合质量仍然存在，这样的特性也使该材料成为太阳能电池和 LED 等物
品的理想选择，甚至可以用于可穿戴电子设备或柔性照明。
而 enoki PET 塑料的超级疏水特性也可能使该塑料成为防细菌定植和血液凝固的医疗器械的理想选择。这种
塑料不仅限于制作实验室样品，在生产过程中，还可以进一步扩大规模。
