Despite the widespread industrial usage of erucamide as a slip additive to modify polymer surface properties, a controversy appears to have persisted regarding the nanostructure of erucamide surface layers, particularly the mol. orientation at the outermost layer. The erucamide nanostructure and mol. orientation, along with its surface coverage, hydrophobicity, and adhesive response, can be tuned by simply varying the erucamide concentration in the solution from which the spin coated layer is prepared Synchrotron X-ray reflectivity (XRR) allowed a comprehensive characterization of the out-of-plane structural parameters (e.g. mol. packing and thickness) of the erucamide layers prepared via spin coating from nonaqueous solution on silica. Complementary Atomic Force Microscopy (AFM) imaging with high lateral resolution revealed localised in-plane structures. Contact angle measurements provided information on the wettability of erucamide-coated surfaces. Peak Force Quant. Nanomech. Mapping (QNM) allowed a correlation between the erucamide nanostructure with the surface nanomech. properties (i.e. adhesive response). Our results reveal erucamide surface nanostructures on silica as patchy monolayers, isolated circular bilayers/rounded rectangle-like aggregates and overlapping plate-like multilayers as the erucamide concentration in the spin coating solution was varied. In all the cases, XRR and AFM results were consistent with the picture that the erucamide tails were oriented outwards. The QNM adhesion force mapping of all the observed morphologies also supported this mol. orientation at the outermost erucamide monolayer. The wettability study further confirmed this conclusion with the observed increase in the surface hydrophobicity and coverage upon increasing erucamide concentration, with the macroscopic water contact angle θ = 92.9° ± 2.9° at the highest erucamide concentration of 2 wt%.cis-13-Docosenamide (cas: 112-84-5) were involved in the experimental procedure.
cis-13-Docosenoamide(cas: 112-84-5) was employed as: standard in determination of fatty acid amides in polyethylene packaging film by GC/MS;slip agent for polymers to reduce their friction coefficient and to make films easier to handle.Product Details of 112-84-5
