Now let's think about this first pi bond, which will be above and below the bonding axis. 让我们先来看这个π键,它在键轴的上面和下面。
The experimental results show that the PI composite films have maintaining the excellent performance of the parent and good bonding properties. 复合薄膜在具备了金属及金属硫化物的优良性能的同时也保持了母体自身聚酰亚胺的优异性能,并且具有良好的粘结性能。
