本研究开发了一种在泡沫相中制备多孔聚合物微球的方法。泡沫相为聚合物、有机溶剂、致孔剂和乳化稳定剂的混合物。该方法由一系列恒定步骤组成，包括材料的均质化、泡沫相的生长和产物的收集。泡沫相的生长是机械搅拌、溶剂蒸发和升温条件下油滴形成的关键。该方法具有省时、高产率和连续化的特点，可用于连续化生产多孔聚合物微球。
This study has developed a method to produce porous polymeric microspheres in a foam phase. And, the foam phase was a mixture of polymer, organic solvent, porogen and emulsion stabilizer. The process was comprised of a series of constant steps homogenization of the materials, growth of the foam phase and collection of the products. The growth of the foam phase was the key which combined mechanical agitation, solvent evaporation and oil droplets development under increasing temperature. The method has been seen time-saving, high yield and continuous process and it could be useful for industrial production of porous polymer microspheres in a continuous process.
