Preparation of Monodispersed Polymeric Microspheres over 50 μm Employing Microchannel Emulsification

摘要: Recently, we proposed microchannel (MC) emulsification, a novel method for making monodispersed emulsion with coefficient of variation less than 5%. In this study, prepared polymeric divinylbenzene microspheres (MS) exceeding 50 μm in diameter by MC emulsification and subsequent polymerization. Using two types plates, MS 86.7 on average diameters 4.8% coefficients variation, as well 69.0 4.1% variation. The can be controlled the terrace length. manner had narrow size distribution did seed effects applied pressures droplet distributions during were investigated. At low pressures, pressure not affect so much, emulsions produced.
