“…It was revealed that the multiphase hybrid filler was able to preserve as well as showed process synergising effect in polymers and elastomers due to the compatibility and co‐operative interactions at the nanoscale. For example, Hybrid filler systems containing CB and carbon nanotube (CNT) ,CB and nanoclay and CB and nanographene/graphene oxide were developed and the resulting rubber nanocomposites demonstrated remarkable improvement in properties taken for their studies.…”

In this work, nitrile rubber (NBR) conventional composites containing 70 phr carbon black (CB) is taken for study. New NBR hybrid composites containing 60 phr of CB and varied halloysite nanotube (HNT) loading of 2, 4, 6, 8, and 10 phr were developed. Experimental investigations were carried out to study the synergistic effect of CB and HNT on the dynamical mechanical properties, solvent resistance, thermal stability and degradation kinetics of NBR hybrid composites. Morphological analysis using X‐ray diffraction analysis (XRD) and Field emission scanning electron microscopy (FESEM) revealed the presence of intercalated structures and formation of local CB‐HNT filler network in the NBR matrix. The glass transition temperatures (Tg) of hybrid composites were raised with the addition of HNT which indicates strong interfacial adhesion between NBR–CB–HNT. Dynamic mechanical analysis and solvent uptake studies revealed that replacement of 10 phr CB by 6 phr HNT in hybrid composites improved the storage modulus by 44% at 30°C and solvent resistance by 29%, respectively. Most importantly, the incorporation of HNT could effectively improve the thermal stability of the NBR hybrid composites according to thermogravimetric analysis and oxidation induction time studies. The activation energy of the thermal decomposition of the hybrid composites increased with the addition of HNT. POLYM. COMPOS., 40:E1612–E1621, 2019. © 2018 Society of Plastics Engineers

Layered double hydroxide (LDH) was in situ modified by sorbic acid (SA) and used to reinforce hydrogenated nitrile rubber (HNBR) by direct blending method. SA connected LDH and HNBR via grafting/coordination mechanism. The results showed that SA could effectively improve the interaction between LDH and HNBR and significantly improve the dispersion of LDH in the rubber matrix. In addition, zinc sorbate (ZDS) formed by the reaction of SA and zinc oxide (ZnO) could self‐polymerize with the initiation of Dicumyl peroxide to form poly‐zinc sorbate, which is conducive to the reinforcement of rubber. The LDH/HNBR composite with SA loading of 20 phr has the best comprehensive mechanical properties, including tensile strength of 39.31 MPa, tear strength of 62.38 kN/m, shore A hardness of 85.1°, and elastic modulus of 20.14 MPa, which is significantly better than the LDH/HNBR composite without addition of SA. Our work provides a practicable and effective methodology for in situ modification of LDH and fabrication of high‐performance rubber composites.
