“啪!”橡皮筋断了。遇到这种情况,我们都知道该去换根新的。不过,法国一组科研人员日前研制出一种可以“自我愈合”的橡皮筋材料,用这种材料制成的橡皮筋断了之后,只需将断裂的两端按住几分钟,就能恢复得完好如初。这种材料经过加热后能熔解,易于回收,所以,它又是一种环保材料。 “Hey!” The rubber band broke. In this case, we all know that we should go for a new one. However, a group of French researchers recently developed a rubber band material that can be “self-healed.” After the rubber band made of this material is broken, it is only necessary to hold the broken ends for several minutes. Can be restored as good as ever. This material can be melted after heating, easy to recycle, so it is also an environmentally friendly material.
