聚氨酯,高分子聚合物,听起来很陌生吧。不过,墙壁、枕头、汽车……这些名词你不会觉得陌生,因为是我们天天接触得到的东西。对于研究材料科学的张之涵叔叔来说,那些高分子材料就是他手上的神奇宝贝,想让墙壁可以随便涂鸦,想让枕头更有弹性,想让汽车座椅更舒适……想让身边的物品更好地满足生活需求,就让材料来充分发挥功能吧。 Polyurethane, polymer, sounds alien to it. However, walls, pillows, cars ... these terms you do not feel strange, because we get in touch every day. For Uncle Zhang Han, who studies materials science, those polymer materials are the Pokémon in his hands, want the walls to be easily graffiti, want the pillows to be more flexible and want the car seats more comfortable ... want the items around you Better meet the needs of life, let the material to give full play to it.
