Durable superhydrophobic nanocomposite materials

Mechanically durable superhydrophobic surfaces.

Development of durable non-wetting surfaces is hindered by the fragility of the microscopic roughness features that are necessary for superhydrophobicity. Mechanical wear on superhydrophobic surfaces usually shows as increased sticking of water, leading to loss of non-wettability. Increased wear resistance has been demonstrated by exploiting hierarchical roughness where nanoscale roughness is p...

Facile preparation of durable and robust superhydrophobic textiles by dip coating in nanocomposite solution of organosilanes.

This article presents a facile approach for the preparation of durable and robust superhydrophobic textiles by simply dip coating in a nanocomposite solution of fluoro-free organosilanes. The superhydrophobic textiles exhibit good water repellency and excellent mechanical, chemical and environmental stability.

Durable Glass Fiber Reinforced Concrete with Supplimentary Cementitious Materials

Durability of concrete structure in marine environments is a big issue for many decades due to chloride attack. Chloride penetrates the concrete structure and accelerates the corrosion process of reinforcement which decreases the life of those structures. Also shrinkage cracks in concrete play main role for chloride penetration through concrete surface.  Many researchers tried to find easy and ...

Wave Propagation in Nanocomposite Materials

Electromagnetic wave propagation is first analyzed in a composite material mde of chiral nano-inclusions embedded in a dielectric, with the help of Maxwell-Garnett formula for permittivity and permeability and its reciprocal for chirality. Then, this composite material appears as an homo-geneous isotropic chiral medium which may be described by the Post constitutive relations. We analyze the pr...
