Effect of Surface-Modified Carbon Nanotubes on the Rheological and Tribological Properties of Urea-Based Gels
The surface-modified molecules of the nanomaterials can interact with the gelator, thereby modulating the self-assembly structure of the gelator molecules. In this paper, to analyze the effect of the surface-functionalized nanomaterial on the self-assembly fiber structure of a urea-based gelator, one-dimensional carbon nanotubes (CNT), hydroxylation (CNTH), and oleic acid-modified (OA/CNTH) carbon nanotubes with “fiber-like” morphology were used as nanomaterials. The results show that the introduction of CNT, CNTH, and OA/CNTH could increase the density, diameter, and cross-linking point of the gel fiber and improve the mechanical stability of the soft nanocomposite. Compared with CNT and CNTH soft-nanocomposite lubricants, OA/CNTH is easier to adsorb to the friction interface, which protects the oxygen-containing lubrication film from friction shear and performs better lubrication.
