摘要： Speriodal polymer beads having a uniform size are prepared by polymerizing uniformly sized 5 monomer droplets formed by dispersing a polymerizable monomer phase over double-walled cylindrical cross-flow membrane into an suspension phase. A shear force is provided at a point of egression of the polymerizable monomer phase into the suspension phase, the direction of shear substantially perpendicular to the direction of egression of the monomer phase. The membrane is metallic and includes a superhydrophobic coating.
