Abstract This paper investigates the effect of hydroxyapatite nanoparticles (HA) on the cure characteristics, tensile and tear strength, elongation at break, hardness, abrasion resistance, heat build-up, resilience, glass transition temperature, oil resistance, alternating current (AC) conductivity and transport properties of chlorinated nitrile rubber (Cl-NBR). The maximum and minimum torque values were increased whereas the cure time values were decreased with the HA content in the Cl-NBR. The uniform dispersion of HA in Cl-NBR was obtained from scanning electron microscopy (SEM) and X-ray diffraction (XRD). Differential scanning calorimetry (DSC) showed the increased glass transition temperature of Cl-NBR with the addition of HA particles. Mechanical properties, conductivity and oil resistance of the composites were greatly increased with the loading of hydroxyapatite. Diffusion results were explained in terms of the loading of nanoparticles and size of the penetrant molecules. Arrhenius and thermodynamic parameters for the diffusion process have been estimated and an anomalous diffusion mechanism was observed.

羟基磷灰石在技术上有用的氯化丙烯腈丁二烯橡胶中作为潜在的纳米填料

摘要 本文研究了羟基磷灰石纳米粒子 (HA) 对固化特性、拉伸和撕裂强度、断裂伸长率、硬度、耐磨性、发热性、回弹性、玻璃化转变温度、耐油性、交流电 (AC) 的影响。氯化丁腈橡胶（Cl-NBR）的导电性和传输性能。最大和最小扭矩值增加，而固化时间值随着 Cl-NBR 中 HA 的含量而减少。HA 在 Cl-NBR 中的均匀分散是通过扫描电子显微镜 (SEM) 和 X 射线衍射 (XRD) 获得的。差示扫描量热法 (DSC) 显示，添加 HA 颗粒后，Cl-NBR 的玻璃化转变温度升高。机械性能，随着羟基磷灰石的负载，复合材料的导电性和耐油性大大提高。扩散结果是根据纳米颗粒的负载和渗透分子的大小来解释的。已经估计了扩散过程的 Arrhenius 和热力学参数，并观察到了异常的扩散机制。
