【摘要】：正蚌类和一些其他软体动物利用黏附蛋白和像塑料一样的坚硬纤维紧紧抓住固体表面。这种纤维具有极强的张力,并且能在内部的一些分子键断裂时进行自我修复。美国加州大学圣芭芭拉分校的Megan Valentine和同事通过模拟蚌类利用的化学现象,创建了拥有相同属性的塑料。铁和一种被称为邻苯二酚的有机化合物之间的分子键使这种材料在保持伸展性的同时很
[Abstract]:Mussels and some other mollusks cling to solid surfaces using adhesion proteins and plastic-like hard fibers. The fiber has strong tension and can repair itself when some of the internal molecular bonds break. Megan Valentine and colleagues at the University of California, Santa Barbara, created plastic with the same properties by mimicking the chemistry of clams. The molecular bond between iron and an organic compound called catechol makes the material extensible.
