Hybrid Functional Surfaces were generated via the novel surface functionalization pathway named Surface Grown Layers (SgL),where the hybrid layers are generated in a single step at a fluid/solid interface via fine tuning of electrostatic complexation between oppositely charged hybrid materials as a function of ionic strength. This simple and novel approach circumvents the drawbacks of multistep layer-by-layer self assembly. The basic criteria of SgL such as,the oppositely charged components must have a good stability towards high ionic strength was better accomplished by hybrid materials composed of inorganic nanoparticle/tubes as core and polymer as corona.This high saline stability feature allows us to switch off/back on the electrostatic interaction between oppositely charged materials by controlled removal of salt via dilution or dialysis.This bulk desalting transition was then stated on a given substrate to develop versatile functional surfaces, possess novel and tunable physicochemical properties and results anti-corrosive, conductive and superhydrophobic surfaces.
