Thickness-dependent molecular arrangement and topography of ultrathin ionic liquid films on a silica surface.
نویسندگان
چکیده
The molecular arrangement and topography of ultrathin ionic liquids (ILs) on a silicon wafer have been studied by AFM and ARXPS, respectively. The results indicate a transition from an "anion-cation" layered (smooth) structure to a "drop-on-layer"/"sponge" (rough) structure when the film gets thicker, which can be attributed to the competition between solid/IL attraction and anion-cation cohesion.

Surface interaction forces of cellulose nanocrystals grafted with thermoresponsive polymer brushes.
The colloidal stability and thermoresponsive behavior of poly(N-isopropylacrylamide) brushes grafted from cellulose nanocrystals (CNCs) of varying graft densities and molecular weights was investigated. Indication of the grafted polymer brushes was obtained after AFM imaging of CNCs adsorbed on silica. Also, aggregation of the nanoparticles carrying grafts of high degree of polymerization was o...
متن کاملPreparation and characterization of ultrathin dual-layer ionic liquid lubrication film assembled on silica surfaces.
A novel ultrathin dual-layer film, which contained both bonded and mobile phases in ionic liquids (ILs) layer, was fabricated successfully on a silicon substrate modified by a self-assembled monolayer (SAM). The formation and surface properties of the films were analyzed using ellipsometer, water contact angle meter, attenuated total reflectance Fourier transform infrared spectroscopy, multi-fu...
متن کاملWettability of Liquid Mixtures on Porous Silica and Black Soot Layers
Sophisticated manipulation of surface roughness and solid surface energy are widely used to design super-hydrophobic layers. In this work, we designed highly porous silica layer with contact angle (CA) of 145°, and its robustness was promoted with thermal treatment. Wettability of coated layer is studied with CA measurement for different liquid surface tensions using diluted organi...

Combining in vacuo deposition of ultrathin ionic liquid (UTIL) films with angle-resolved X-ray photoelectron spectroscopy (ARXPS), we demonstrate that by deposition of submonolayer amounts of Pd onto Au(111) the initial growth mode of the ionic liquid (IL) 1-ethyl-3-methylimidazolium trifluoromethanesulfonate ([C2C1Im][OTf]) can be switched from three-dimensional (3D) to two-dimensional (2D) gr...
متن کاملImidazolium-based ionic liquids immobilized on solid supports: effect on the structure and thermostability.
[BMI][PF(6)] has been supported on silica and alumina in order to study the effect of these classical oxide supports on the structure of the ionic liquid. A widespread characterization by TGA, DSC, XRD and solid NMR of thin films of [BMI][PF(6)] immobilized on these amorphous supports has evidenced a dramatic effect on the ionic liquid structure depending on the nature of the support. For the a...
