Ceramic microspheres have attracted significant attention, while the preparation of hierarchically porous ceramic microspheres with high porosity, good sphericity, and controllable size or shape in a short time remains a challenge. Herein, we developed a highly adaptable methodology for the preparation hierarchically porous ceramic microspheres with high porosity and favorable shape in a short time. The UV-curing assisted molding method combined with the Pickering emulsion method was utilized to prepare hierarchically porous ceramic microspheres. Under the irradiation of a UV-curing lamp (395 nm, 50 W), the Pickering emulsion can be cured within as short as 10 s. The microstructures of the three microspheres with different shapes were characterized by scanning electron microscopes (SEM). The as-prepared microspheres had a high sphericity, the interconnectivity of pores was as high as 54 %, and its porosity was as high as 73.4 % ± 3.0 %, while the density was quite low at ∼ 1.02 g/cm3.

基于紫外光固化辅助成型的分级多孔陶瓷微球的快速制备

陶瓷微球受到了极大的关注,而在短时间内制备具有高孔隙率、良好球形度、尺寸或形状可控的分级多孔陶瓷微球仍然是一个挑战。在此,我们开发了一种适应性强的方法,可在短时间内制备具有高孔隙率和良好形状的分级多孔陶瓷微球。采用紫外光固化辅助成型法结合Pickering乳液法制备了分级多孔陶瓷微球。在紫外光固化灯 (395 nm, 50 W) 的照射下,Pickering 乳液可在短短 10 秒内固化。通过扫描电子显微镜(SEM)对三种不同形状的微球的微观结构进行了表征。制备的微球具有较高的球形度,3 .
