科学家日前研制出一种可“自愈”的仿生人工合成塑料,该塑料被划伤时会像皮肤出血一样流出红色液体,但随着光照、温度和酸度变化,伤口能自动愈合。科学家称,这种材料有望用于手机、电脑外壳、汽车清漆甚 Scientists have developed a biodegradable synthetic plastic that can “self-heal” a plastic that bleeds out of the red liquid just as skin bleeds when scratched, but automatically heals as the light, temperature and acidity change. Scientists said the material is expected to be used in cell phones, computer cases, car varnishes
