RETRACTED: Synthesis and Characterization of Carbon Black-Halloysite Nanotube Hybrid Composites Using XRD and SEM

Composite materials are the leading emerging materials over the past twenty years since its introduction. Among the natural composites, carbon black-halloysite nanotubes hybrid composite is one of the recent emerging sector in the composite field, because of its high strength with less density as compared to the metal matrix composite. In this research carbon black-halloysite nanotubes hybrid composites based on synthetic rubber copolymer of acrylonitrile and butadiene were prepared and tested. The carbon black loading was kept fixed at sixty per hour and halloysite nanotube loading was varied from zero to ten parts per hundred rubbers per hour. The effect of carbon black-halloysite nanotube hybrid fillers on the curing behaviour, mechanical properties and morphology of the high nitrile rubber nanocomposites were investigated. The cure characteristics showed that the scorch time and cure time increased with the halloysite nanotube loading. The maximum torque exhibited an increasing trend from zero to six per hour. The tensile properties which exhibited an increasing trend until an optimum loading of six per hour were mainly influenced by the high nitrile rubber-carbon black-halloysite nanotube interaction and the intercalation of rubber and carbon black into the tubules. X-ray diffraction test and scanning electron microscope studies were supported to the results obtained.
