The development of super-hydrophobic surfaces has been inspired by natural systems and uses a number of novel (nano) technologies. Superhydrophobicity has stimulated much scientific and industrial interest because of applications in water repellency, selfcleaning, friction reduction, antifouling, etc. Despite its inherent hydrophilicity, cellulose has unparalleled advantages as a substrate for ...

Alkali activated materials (AAMs) were considered as economical and environmentally friendly that have attracted incrementally attention green coating materials. However, alkali inclined to be infiltrated ruined by harmful ions in water due their hydrophilicity. And the ordinary ways of construct superhydrophobic coatings costly, complex need fluorine material. The surfaces fragile owing super-...

Hydrophobic Mg(OH)2/calcium myristate (Ca[CH3(CH2)12COO]2, CaMS) and Mg(OH)2/magnesium (Mg[CH3(CH2)12COO]2, MgMS) composite coatings were prepared on the alkali-treated AZ31 substrates via both electrodeposition dipping methods. The morphologies, compositions, constitutes of investigated by using field-emission scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS), Fourier ...

The surface characterization of 'soft' materials presents a significant scientific challenge, particularly under 'wet' in situ conditions where a wide variety of non-covalent interactions may be relevant. Here we introduce a new chemical imaging method, MAPT (mapping using accumulated probe trajectories) that generates images of surface interactions by distributing different aspects of molecula...

In this study, the thermal, chemical and structural stability of 1H,1H,2H,2H-perfluorodecyl acrylate polymers (p-PFDA) synthetized by initiated chemical vapor deposition (iCVD) were investigated. PFDA polymers are known for their interesting crystalline aggregation into a lamellar structure that induces super-hydrophobicity and oleophobicity. Nevertheless, when considering applications which in...

After a brief presentation of the classical laws of wetting, we review di(erent phenomenological descriptions of rough wetting, i.e., show how these classical laws must be modi*ed on rough solids. This introduces the questions of hemi-wicking (can a *lm propagate inside the texture of a solid ?), rough *lms (is it possible for a liquid *lm to follow the roughness of a solid ?) and super-hydroph...
