Abstract
Porous cross-linked microspheres were manufactured from low-viscosity monomers through electrospraying combined with photopolymerization. Firstly, the liquid drops of monomer solution formed by electrospraying were crystallized by liquid nitrogen, and then the cross-linked polymer is formed by photopolymerization. Finally, the porous microspheres were obtained after the solvent was removed by freeze drying. The morphology, chemical structure, pore diameter and thermal stability of porous cross-linked microspheres were investigated by scanning electron microscope (SEM), fourier transform infrared spectroscopy (FTIR spectroscopy), mercury intrusion porosimetry and thermogravimetry analysis (TG). This approach provides a new stratage to prepare cross-linked porous microspheres from small molecules without using any template or other additives.
