Investigation of Changes in Hydrophilicity of Emulsion Porous Polymer Poly (Styrene-Divinylbenzene) Functionalizing

Emulsifying porous polymers have many pharmaceutical and industrial applications and are considered as new materials for separation. In this research, first the emulsion synthesis of poly (styrene-di vinylbenzene) was performed and then the effect of increasing the functional group of sodium styrene sulfonic acid on the hydrophilicity of the emulsion porous polymer poly (styrene-divinylbenzene) was investigated. Scanning Electron Microscope to study surface morphology and determine the size distribution of surface cavities and Energy Dispersive X-ray analysis test to investigate the presence of sulfur and sodium atoms in the surface of functionalized porous polymer and contact angle measuring device with Coupled-Camera Devise(CCD) and with software for measuring the contact angle of droplet contact with the surface to evaluate the hydrophilicity of the surface of polymerized emulsion polymer poly (styrene-divinylbenzene) were used. Increasing sodium styrene sulfonic acid has no effect on the shape and size of the cavities formed, but the hydrophilicity of the samples increased with increasing sulfone factor in the aqueous phase and the appropriate percentage of sodium styrene sulfonic acid in the aqueous phase was about 2%. With an increase of more than 2%, a slight increase in the hydrophilicity of the surface of the emulsion porous polymer poly (styrene-divinylbenzene) was activated and the graph became almost flat with slope changes insignificant.
