AbstractTwo different polymers, poly(vinylbenzyl chloride) and poly(methyl methecrylate-2-hydroxyethyl methacrylate), were respectively employed as the major component of the particle material and amphiphilic polymer methoxy poly (ethylene glycol)-b-poly (D, L-lactide) was employed as an essential additive. Gigaporous microspheres which possess flow-through pores which range from submicron to micron scale were prepared by two-step emulsification, emulsion ripening, and solvent extraction. Parameters on the final morphology were particularly investigated, including the polymer component, emulsion ripening time, and osmotic gradient. The formation mechanism of gigapores was also discussed with consideration of evolution behavior of the double emulsion system. The evolution process was proved crucial to control the final pore structure. Such kind of gigaporous microspheres could be further exploited as a promising chromatographic media for the purification of bioproducts.
