The surface properties of the OSW and NLS are measured with the dynamic contact-angle technique. The x-ray photoelectron spectroscopy (XPS) of the OSW reveals that the OSW possesses various reactive functional groups namely hydroxyl groups (OH). Hybrid filler from NLS and OSW were incorporated into carboxylated nitrile rubber (XNBR) to produce XNBR hybrid composites. The reaction of OH groups from the OSW with COOH of the XNBR is checked by attenuated total reflectance spectra (ATR-IR) of the composites. The degree of curing DM (maximum torque-minimum torque) as a function of hybrid filler as derived from moving die rheometer (MDR) is reported. The stress-strain behavior of the hybrid composites as well as the dynamic mechanical thermal analysis (DMTA) is studied. Bonding quality and dispersion of the hybrid filler with and in XNBR are examined using scanning-transmission electron microscopy (STEM in SEM).

Resumo: Neste trabalho foi estudado o efeito Payne como uma medida das interações carga-carga e polímero-carga em nanocompósitos de montmorilonitaorganofílica (MMTorg) e borracha nitrílica (NBR), usando o Analisador de Processamento de Borracha -RPA 2000. Os nanocompósitos de NBR e MMTorg foram preparados em um misturador de rolos e o efeito Payne foi avaliado em compostos não vulcanizados tipo goma pura e contendo 5, 10, 15 e 20 phr de MMTorg. Os resultados mostraram que a composição com 5phr de MMTorg apresentou melhor interação polímero-carga como consequência da menor quantidade de aglomerados de carga na matriz elastomérica. Palavras-chave: Nanocompósito, montmorilonita organofílica, efeito Payne, borracha nitrílica, RPA 2000. Payne Effect in NBR Nanocomposites with Organofilic MontmorilloniteAbstract: In this work the Payne effect was evaluated as a measure of the filler-filler and filler-polymer interactions in nanocomposites of organomontmorillonite (MMTorg) on acrylonitrile-butadiene-rubber (NBR) by using the Rubber Process Analyzer -RPA 2000. The nanocomposites of NBR and MMTorg were prepared on a Berstorff two-roll mill and the evaluation of the Payne effect was carried out in unvulcanized pure gum and varying the MMTorg content from 5, 10, 15 and 20 phr. The composition with 5 phr of MMTorg showed the best filler-polymer interaction as a consequence of the smaller amount of agglomerates of the filler in the elastomeric matrix.

“…These functional groups increase the bonding between the CBs and rubber, which results in stronger interfacial adhesion compared to the case when untreated CBs are used. Various surface treatment methods may be applied to CBs, including chemical, plasma, ozone, electrochemical, and heat treatment [44][45][46][47][48][49][50][51][52][53][54].…”

Carbon blacks (CBs) have been widely used as reinforcing materials in advanced rubber composites. The mechanical properties of CB-reinforced rubber composites are mostly controlled by the extent of interfacial ad hesion between the CBs and the rubber. Surface treatments are generally performed on CBs to introduce chemical functional groups on its surface. In this study, we review the effects of various surface treatment methods for CBs. In addition, the preparation and properties of CB-reinforced rubber composites are discussed.
