Abstract Hydrogenated carboxylated acrylonitrile–butadiene rubber (HXNBR) and multi-walled carbon nanotubes (MWCNT) composites were prepared. The dispersion of MWCNT in HXNBR matrix was evaluated by field emission scanning electron microscopy. HXNBR/MWCNT composite had shorter scorch time and optimum curing time compared with that of unfilled HXNBR. The tensile strength and modulus of HXNBR/MWCNT composites increased with increasing MWCNT content. Mooney–Rivlin equation was used to describe the stress–strain behavior of unfilled HXNBR and the strain amplification factor was taken into account for HXNBR/MWCNT composites. The Mullins effect and dynamic mechanical properties of HXNBR/MWCNT composite were also investigated.

多壁碳纳米管增强氢化羧化丁腈橡胶

摘要 制备了氢化羧基丁腈橡胶（HXNBR）和多壁碳纳米管（MWCNT）复合材料。通过场发射扫描电子显微镜评估多壁碳纳米管在 HXNBR 基体中的分散。与未填充的 HXNBR 相比，HXNBR/MWCNT 复合材料具有更短的焦烧时间和最佳固化时间。HXNBR/MWCNT 复合材料的拉伸强度和模量随着 MWCNT 含量的增加而增加。Mooney-Rivlin 方程用于描述未填充 HXNBR 的应力-应变行为，并考虑了 HXNBR/MWCNT 复合材料的应变放大系数。还研究了 HXNBR/MWCNT 复合材料的穆林斯效应和动态力学性能。
