在高速均质条件下，采用一锅悬浮聚合法制备高折叠交联聚合物微粒。皱折是交联微粒中溶剂蒸发的结果。研究了微颗粒交联密度和溶剂对聚合物的影响。结果表明，中等交联密度（DVB/St = 0.5）最适合产生褶皱最多的表面，且溶剂含量越高，表面褶皱越深。该方法非常简单，原则上可用于生产具有其他化学成分的褶皱微粒。
A facile method of preparing highly folded cross-linked polymeric microparticles has been developed via one-pot suspension polymerization under high-speed homogenization. The wrinkles result from the evaporation of solvent in the cross-linked microparticles. The effects of microparticle cross-linking density and solvent on the polymer have been studied in detail. It was found that a medium cross-linking density (DVB/St = 0.5 by weight) is optimal for producing the most folded surface and the higher the solvent content, the deeper the surface wrinkles. This method is very simple and in principle can be applied to produce wrinkled microparticles with other chemical compositions.
