发现扫描隧道显微镜可对聚苯乙烯超微粒子进行观察。用水悬浮液及苯饱和溶液使聚苯乙烯表面溶胀后，都可得到清晰的STM像，并首次从溶胀表面的高分辨率STM像观察到高分子链的精细结构和链的镶嵌式自组装形态。
Scanning tunneling microscopy was used to observe polystyrene ultrafine particles. After the surface of polystyrene was swollen with aqueous suspension and benzene saturated solution, a clear STM image was obtained. For the first time, the fine structure of polymer chain and the mosaic self-assembled chain were observed from the high resolution STM images on the swollen surface .
