Concentration dependent wetting by aniline-ethanol binary system

Vinjanampaty Madhurima, Jonathan Lalnunsiama

Abstract


Wetting of five substrates namely glass, indium tin oxide, aluminum oxide, hylam and teflon by aniline-ethanol binary system over the entire concentration range is studied using contact angle measurements. Rapid wetting of the substrates, especially hylam in the aniline rich region is understood in terms of the surface energies of the substrates and the intermolecular interactions between the two moieties. FTIR, dielectric and conformational analysis are used to study the molecular interactions in the binary system.
