The influence of low-temperature plasma modification of bentonite on the dynamic-mechanical properties and vulcanization of rubber mixtures was examined. EDX, FTIR and TGA analysis were used to evaluate the filler. IR spectra of modified bentonite indicate lower intensity of the bands associated with OH groups and water. TGA confirms a smaller weight loss of samples subjected to plasma treatment, which also proves a lower water content in the mineral, confirming the effectiveness of the plasma treatment used.

The application of cellulose (CEL) as a filler in elastomeric composites (ECs) was studied, with cellulose examined in its untreated form (RAW), after DCSBD plasma modification, and ozone pre-treatment. Changes in surface fluorescence demonstr...

The changes of rubber blend surface induced by atmospheric plasma at several conditions were studied via FTIR, SEM, contact angle and adhesion measurement. After plasma, the presence of OH, COO^- bands of higher intensity was observed, whilst methylene groups reduced. A several formations of weaker agglomeration and cleaning of the surface was recognized. Also an intense decline of contact angles was observed. The plasma induced significantly greater changes at the 0.5 mm position, whereas emission times of 10 s and 30 s did not significantly affect the modifications of the investigated surface.

Instead of conventional carbon black, an alternative carbon filler (ACB) obtained in the pyrolysis process from tire waste was used for rubber compounds. The fillers were characterized using FTIR and TGA methods. The mechanical properties of the obtained rubber compounds and the influence of the fillers used on the vulcanization process, as well as the Payne effect, were examined. The results confirm the possibility of replacing conventional carbon black with an alternative carbon filler in rubber compounds.
