Figure 1b contains the representative SEM image of the polystyrene nanospheres synthesized by dispersion polymerization, showing that spherical polymeric beads with smooth surfaces could be fabricated.
PU-PI effectively stabilized the polymeric particles in photoinitiated dispersion polymerization due to the unique stabilization process.
Monodispersed PMMA (polymethyl methacrylate) particles were prepared via a dispersion polymerization process using methanol as the dispersive medium, azobisisobutyronitrile (AIBN) as initiator, and polyvinylpyrrolidone (PVP) as steric stabilizer.
Since most researches are focused on emulsion polymerization, robust recipes for the particle synthesis are still necessary to prepare polymeric beads dispersed in organic solvent by proper synthesis method such as dispersion polymerization [16].
Since the miscibility of styrene decreases with increasing amount of water, the addition of water may cause the gradual change from dispersion polymerization to emulsion polymerization, resulting in the size reduction of the polymeric particles.
After the polymeric latex beads suspended in ethanol they were prepared by dispersion polymerization, they were emulsified with oil phase such as hexadecane by mechanical homogenization.
The polystyrene nanosphere suspension synthesized by dispersion polymerization was washed by centrifugation and redispersion in fresh ethanol to prepare dispersed phase.
The dispersion polymerization was performed at 70 °C.
The PAT PSS colloidal particles were synthesized using dispersion polymerization.
