Modification of Polycaprolactone microspheres surface by ultra violet/ozone treatment to improve its hydrophilicity

Unloaded microspheres were prepared from Polycaprolactone (PCL) using an oil-in water emulsion solvent evaporation method. The microspheres with the size distribution in a range of 150-200 µm were then treated by exposed the microspheres under ultra violet irradiation and simultaneously aerated with...
