| Popis: | Simultaneous achievement in high solid content and high microsphere yield is deemed a challenge in the fabrication of monodisperse microspheres by precipitation polymerization. We herein demonstrate that micro-sized monodisperse poly(methacrylic monomer-divinylbenzene) microspheres containing epoxy, lauyl, carboxyl and hydroxyl functions can be fabricated by solvothermal precipitation co-polymerization at 20% (mass) monomer loading with over 94% microsphere yield. The morphology and porosity of the obtained particles can be readily tuned by cosolvent-acetonitrile binary solvents. Addition of a small amount of cosolvent that has similar solubility parameter to that of the functional monomer can significantly improve the monodispersity of the obtained microspheres. When tetrahydrofuran was used as the co-solvent, the surface area of the highly porous microspheres achieved higher than 400 m2·g−1. Solvothermal precipitation co-polymerization can be expected in scale-up fabrication of various monodisperse functional microspheres free of any surfactant and additive. |
