The Concept of Miscellaneous DCSBD Plasma Technique To Accomplisch Suitable Structural Properties of Tire Rubber

A model tire rubber blend was subjected to the diffuse coplanar surface barrier discharge DCSBD working in ambient air in order to investigate structural differenties. Additionally, a multiple plasma treatment conditions were performed. The first condition was the applied exposure time, when examined rubber was exposed to DCSBD plasma for 10 s, 30 s, 1 min and 1.5 min. Another factor was the location of the treated rubber on the plasma electrode and the chemical composition of model blend. The structural analysis was carried out by FT-IR spectroscopy using a diamond crystal by means of identification of novel functional bonded species. Furthermore, the elementary analysis was linked by EDX spectroscopy and morphology was studied by SEM microscope. Also the wetting properties were studied. Overall, the efficiency of DCSBD plasma source has been mostly proved to be suitable for blend surface modification in order to improve its surface structural characteristics mainly in lower exposure times.
