Surface modification of biomaterials in the dielectric barrier discharge

The work deals with the treatment of surfaces of various polymeric biomaterials using a plasma generated at atmospheric pressure. Plasma is generated between two electrodes among which is inserted dielectric material. By using this type of discharge, the difference of treated material surface quality is being examined, ie. surface energy and contact angle according to the time of processing. Evaluation of the results of surface analysis was performed by the method of measuring the contact angle and surface energy using the apparatus See System. The goal was to compare the surface quality change, before and after processing in the plasma, as also its dependency on the time of aging. The results differs according to the type of material
