Abstract
Synthesis of organic/inorganic hybrid materials is an area of growing interest as advantageous properties of disparate components can be combined into singular materials. In this study, nanosized silica gel hybrids were obtained by reaction between silanol groups of silica and 2,4-dichloro-6-methoxy-1,3,5-triazine (DCMT), which then reacted with p-phenylenediamine. Acylation of amine by 10-undecanoic acid, N-Fmoc-Lys(Boc)OH, and N-Boc-Ser(OH)OH was the final step. Friction performance of silica–triazine hybrids, evaluated with a microtribometer, can be ranked in the following order: 10-undecanoic acid >N-Fmoc-Lys(Boc)OH>p-phenylenediamine>N-Boc-Ser(OH)OH. It is inferred that all the hybrids are effective in reducing friction, in comparison to pure silica materials. The rearrangement of silica–triazine hybrid included the 10-undecanoic acid, induced by UV exposure, also confirmed further improvement of friction performance. This approach can be successfully applied to preparation of other ORMOSIL hybrids.
