Tensile strength and elongation of NBR/PVC/CuFe 2O 4 magnetic nanocomposites: a response surface methodology optimization
Abstract
This paper reports the development of nitrile butadiene rubber (NBR) nanocomposite toughened by the combination of polyvinyl chloride (PVC) and CuFe 2O 4 nanoparticles (NPs). CuFe 2O 4 NPs synthesized by sol–gel auto-combustion route. Response surface methodology was applied for optimization and modelling of the tensile strength and elongation of NBR/PVC/CuFe 2O 4 nanocomposite. By using XRD, SEM, EDX and VSM, we characterized CuFe 2O 4 NPs and the optimized NBR/PVC/CuFe 2O 4 nanocomposite, and investigated the mechanical properties of NBR/PVC/CuFe 2O 4 nanocomposite. Results showed that the surface cracking of NBR decreased as the PVC and CuFe 2O 4 content increased, which leads to better mechanical properties of NBR. © 2020, Indian Academy of Sciences.
