“…Several studies claim that highly exfoliated structures of the clay are important requirement to achieve better performance of the corresponding nanocomposites. However, fully exfoliated rubber/ clay nanocomposites are very difficult to obtain, especially with the melt mixing procedure, because of the high viscosity of the rubber in the molten state [13,28] . In spite of it, several clay-based nanocomposites displayed a great improvement of mechanical performance even with non-exfoliated structures [17] .…”

Nitrile rubber - based nanocomposites prepared by melt mixing: effect of the mixing parameters on mechanical, dynamic-mechanical and creep behavior

Nanocomposites constituted by nitrile rubber matrix and Cloisite 15A (OC15A) as the organoclay were prepared by melt blending and cured with the m-phenylene-bis-maleimide (BMI)/dicumyl peroxide (DCP) system. The effect of mixing parameters on the clay dispersion was evaluated, including mixing temperature and time, and rotor speed of the internal mixer. The organoclay effectively accelerated the vulcanization reaction of NBR, which was attributed to the presence of the alkylammonium salt as the intercalant. All nanocomposites displayed improved tensile properties indicating a good reinforcing action of the clay. Also, the creep compliance was substantially reduced with the incorporation of the clay. X-ray diffraction studies showed the presence of intercalated and deintercalated clay population. The mixing parameters did not have an important effect on clay dispersion and properties of NBR-clay nanocomposites, except for the creep behavior.

“…These results suggest an increase of the curing rate promoted by the quaternary alkylammonium salt present as the intercalant for the organoclay. Similar results have been observed by other authors [9,28] . The maximum torque also increased with the presence of clay.…”

“…In these reports we showed that the agro polymer based OSW was able to reinforce the XNBR vulcanizate which permit the usage of such materials without using compatibilizers but the eye was kept open on further improvement of the performance of the composites without chemical modification of the filler. From various studies on nano composites, the incorporation of the nano filler into polymer matrix increases the strength as well as the modulus of the composites [11][12][13][14][15][16] . The high surface area and aspect ratio of the nano filler makes it suitable candidate to balance the adverse effect of the irregularities of the lignocellulosic fillers.…”

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).

“…In BR as the matrix, best mechanical properties were obtained with a Mt having dimethyl dihydrogenated tallow quaternary ammonium as the compensating cation [107], an ammonium cation largely diffused in RCN field. In a SBR matrix, mechanical properties improved up to 10 phr of OC (Mt/octadecyltrimethylamine, Nanomer I.28E) [87] (Mousa and Karger-Kocsis, 2001), decreasing for a further addition. In a nanocomposite based on maleic anhydride modified EPM (EPM-MA, with 0.42 wt% of maleic anhydride) about 5% of OC (Mt/octadecyl amine) gave a modulus three times higher than that of EPM-MA.…”
