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

本文报道了通过聚氯乙烯（PVC）和\（\ hbox {CuFe} _ {{\ mathrm {2}}} \ hbox {O} _ {\ mathrm的组合而增韧的丁腈橡胶（NBR）纳米复合材料的发展{4}} \）纳米粒子（NPs）。\（\ hbox {CuFe} _ {{\ mathrm {2}}} {\ hbox {O}} _ {{\ mathrm {4}}} \）通过溶胶-凝胶自动燃烧路线合成的NP。将响应面方法应用于\（\ hbox {NBR / PVC / CuFe} _ {{\ mathrm {2}}} \ hbox {O} _ {{\ mathrm {4} }} \）纳米复合材料。通过使用XRD，SEM，EDX和VSM，我们对\（\ hbox {CuFe} _ {{\ mathrm {2}}} \ hbox {O} _ {{\ mathrm {4}}} \）进行特征化和优化\（\ hbox {NBR / PVC / CuFe} _ {{\ mathrm {2}}} \ hbox {O} _ {{\ mathrm {4}}} \）纳米复合材料，并研究了\（\ hbox {NBR / PVC / CuFe} _ {{\ mathrm {2}}} \ hbox {O} _ {{\ mathrm {4}}} \）纳米复合材料的力学性能。结果表明，随着PVC和\（\ hbox {CuFe} _ {{\ mathrm {2}}} \ hbox {O} _ {{\ mathrm {4}}} \）含量的增加，NBR的表面裂纹减少，从而导致NBR的机械性能更好。
