Abstract :
In the present work ,NBR/PVC conventional composites containing 70phr Carbon black(CB) and NBR/PVC hybrid nanocomposites containing a fixed amount of CB (60phr) and varying amount of halloysite nanotubes(HNT) with 0 to 6phr were prepared by melt -mixing method using a two roll open mill. The effect of CB-HNT hybrid fillers on the morphology and mechanical properties of the NBR/PVC composites have been investigated. The tensile strength ,elongation at break, 100% modulus, swelling ratio and tear strength of the NBR/PVC hybrid nanocomposites are increased by 12.87%,13.91 %,14.54%, 25.97 % and 33.72 % respectively compared to the conventional composites .Hardness and Compression set have significantly improved compared to the conventional composites .XRD studies reveal the intercalation of NBR/PVC chains ,CB and other ingredients into the HNT galleries and formation of intercalated structures. Synergistic effect of CB-HNT hybrid fillers, improved NBR/PVC-CB-HNT interfacial interactions and formation of intercalated structures are believed to be responsible for the superior mechanical properties of the NBR/PVC hybrid nanocomposites.
