摘要: 介绍了利用筛网设计制作出的一种新型的反弹盘，并用于聚α-甲基苯乙烯（PAMS）微球的弹跳实验。分析了筛网盘与玻璃盘之间的差别和由此带来的对PAMS微球弹跳性能影响。通过实验分别研究了筛网盘相关的参数对微球表面粗糙度的影响。结果表明：采用筛网盘与玻璃盘相比，PAMS微球的弹跳性能的改善非常明显；筛网盘的使用较好地解决了在无等离子体的镀膜环境下（如热蒸发的方法制备PAMS微球表面聚酰亚胺涂层）PAMS微球的弹跳问题；为降低微球表面粗糙度，反弹盘应采用间歇振动的模式。Abstract: In this paper, mesh pans for coating poly-olphe-methycstyrene(PAMS) microspheres with polymer are designed. The difference between bounces on a mesh pan and a glass pan is evaluated. The capability of mesh pans for bouncing PAMS microspheres is examined. The effect of the related parameters of the mesh pans on the surface roughness of the microshells has been explored. The experimental results show that the mesh pans improve significantly the bounce of PAMS microspheres in comparison with glass pans. In order to improve the surface roughness of microspheres, an intermittent vibration mode must be applied on the mesh pans for bouncing the microsphere．
