日本的Zeon公司已发现一种石油树脂——聚降莰烷(polynorbornane)具有形状记忆功能。甚至当它的形状被改变得很厉害时,对它加热便立即会恢复原状。Zeon公司准备在市场上销售用该材料制作的被命名为“NorsoLex”的汽车保险杠。聚降莰烷是一种高分子,其分子量超过两百万。比普通的高分子大十倍以上。这种具有微孔的树脂正在引起人们强烈的关注。 CdF化学公司是法国化学品生产的主要厂家,它开发了这种树脂的合成技术,并探讨了该树脂作为液体吸收材料的应用。这家公司向世界上的制造 Japan’s Zeon Company has found that a polynorbornane, a petroleum resin, has a shape memory function. Even when its shape is changed so drastically, it is immediately restored to its original shape by heating it. Zeon plans to market a car bumper named “NorsoLex” made of this material on the market. Poly (norjane) is a polymer with a molecular weight of more than two million. Ten times more than ordinary polymer. This kind of microporous resin is arousing strong concern. CdF Chemicals, a major producer of French chemicals, has developed the resin synthesis technology and explored the use of the resin as a liquid absorbing material. This company is made to the world
