Facile method to prepare monodisperse polystyrene particles by hydrothermal process

Brilliant white polystyrene microsphere film as a diffuse back reflector for solar cells

“…Monodisperse PS microspheres were synthesized by combining a hydrothermal process with a dispersion polymerization process as employed in our previous work [11], whose negative surface charges rendered them stably dispersed in ethanol/water solution. Then some de-ionized water was added to form a sphere concentration of 2 wt%.…”
