METHOD OF OBTAINING POROUS POLYMER STRUCTURE USING ATMOSPHERIC PRESSURE PLASMA

This study focuses on producing porous polymer under plasma conditions using two different monomers: ethylene glycol and styrene. A plasma discharge at atmospheric pressure was used to induce polymerisation reactions in order to obtain copolymer films based on the two monomers. The plasma source consists of a dielectric barrier discharge which operates in an argon gas flow with glass as dielectric. The porous polymer was obtained by dissolution and sonication of the hydrophilic groups from the material. The new porous material was tested in terms of protein adsorption. The films were characterized by Fourier Transform infrared spectroscopy, X-ray Photoelectron Spectroscopy and Scanning Electron Microscopy techniques.
