Silsesquioxanes-Based Nanolubricant Additives with High Thermal Stability, Superhydrophobicity, and Self-cleaning Properties

摘要: Nanoadditives are promising materials for long-envisioned next-generation lubricants to achieve excellent tribological performance and thermal stability. Here, an instigative novel approach has been scrutinized facilely prepare the nanolubricant additive. For this purpose, three synthetic strategies were designed i) preparation of uniform-sized poly(methyl silsesquioxane) (PMSQ) nanoparticles, ii) hydrosilylation long carbon chain ethyl 10-undecenoate iii) modification PMSQ nanoparticles with product through a condensation reaction, in order obtain long-carbon-chain grafted nanohybrids. The morphology, composition, properties these nanohybrids confirmed by 1H-NMR, FTIR, SEM, EDS, TGA. effects different concentrations unmodified modified on silicone oil discussed. In comparison one performs very well reduce coefficient friction wear scar diameter at low concentration. TGA results revealed extraordinary stability particles, as their weight loss was only 19% 800 °C which is remarkably higher than other solid lubricant additives. research, we tried fill deficiency thermally stable material field heavy machinery industry. addition, environment-friendly (fluorine-free), superhydrophobic self-cleaning surface effect also observed. These silsesquioxane-based having synergistic effects, advantageous scientific values, application prospects expected be more useful longer chains.
