Abstract

Dodecenylsuccinic anhydride was used as a surface modifier to further modify amino-functionalized silica nanoparticles, and the modified nanoparticles (RNS-1A-DDSA) showed good dispersion stability in both nonpolar PAO6 and polar DIOS base oils. The tribological properties of RNS-1A-DDSA were evaluated using an oscillating reciprocal friction and wear tester (SRV-5), and it was found to exhibit excellent tribological properties in both base oils with different polarities. EDS and SEM were used to characterize the wear surfaces, and combined with the results of AFM and QCM adsorption experiments, the reason for the applicability of RNS-1A-DDSA in both polar and non-polar base oils was deduced.

对极性和非极性基础油都具有良好适用性的二氧化硅纳米添加剂的制备和摩擦学特性

使用十二烯基琥珀酸酐作为表面改性剂对氨基官能化纳米二氧化硅颗粒进行进一步改性，改性后的纳米颗粒（RNS-1A-DDSA）在非极性 PAO6 和极性 DIOS 基础油中均表现出良好的分散稳定性。使用摆动往复摩擦磨损测试仪（SRV-5）对 RNS-1A-DDSA 的摩擦学特性进行了评估，发现它在两种不同极性的基础油中都表现出了优异的摩擦学特性。利用 EDS 和 SEM 对磨损表面进行了表征，并结合 AFM 和 QCM 吸附实验的结果，推断出了 RNS-1A-DDSA 在极性和非极性基础油中均适用的原因。
