The Development of Chemical Bimetal

双金属是由两块膨胀率不同的金属板组成的。当温度升高时，两块金属板的长度就会不同。那么，双金属是弯曲的。我们将这一原理扩展到化学反应中，并开发了化学双金属。化学双金属由两块板组成。一个盘子不会改变长度。相反，另一板则是通过化学反应，如反应物质的溶解或相变化来改变长度的。研制了化学双金属亚胺二乙酸树脂。在PET膜上聚合了氯苯、苯乙烯和二乙烯苯。其次，介绍了该膜的亚氨基二乙酸酯。螺旋弹簧化学双金属比传统的化学双金属具有更高的灵敏度，因为它的长度更长。同时，它的输出可以从主轴的旋转中取出。然后在PET膜上聚合亚氨基二乙酸-苯乙烯、苯乙烯和二乙烯苯。对样品溶液为弱碱的化学双金属进行了计算机模拟。此外，还进行了含离子对生成反应的模拟。模拟结果与实验结果吻合较好。

Bimetal is composed of two metal plates which have different rates of expansion. When the temperature rises, the length of two metal plates become different. Then, bimetal is curved. We extended this principle to the chemical reaction and developed the Chemical Bimetal. The Chemical Bimetal consisted of two plates. One plate does not change the length. On the contrary, another plate changes the length by chemical reaction, such as dissolution of reaction material or phase change.The iminodiacetic resin Chemical Bimetal was developed. Chlorostylene, stylene, and divinylbenzene were polymerized on PET membrance. Next, this membrane were introduced iminodiacetate.The Spiral Spring Chemical Bimetal has sharper sensitivity than the conventional Chemical Bimetal, because it has longer length. Also, it's output can take out from the rotation of spindle. Then, Iminodiacetic-stylene, stylene, and divinylbenzene were polymerized on PET membrane.Computer simulations of the Chemical Bimetal in the case that sample solution were weak bases were done. Also, simulations which contain ion-pair formation reaction were done. These simulations well agreed with experimental results.
