Paper Abstract

Molecularly-ordered thin-films comprised of nano-sized inorganic particles and ionic polymer molecules have been fabricated on single crystal silicon, quartz, and glass substrates by a novel molecular self-assembly process. X-ray photoelectron spectroscopy indicates that the formed cationic inorganic particles only adsorb on negatively charged and not on positively charged surfaces. Contact angle measurements demonstrate that the water contact angle oscillates regularly according to which ions form the outermost layer of the films. Thin-films ordered at the molecular level have been formed up to several hundred layers in thickness and characterized by UV/Vis spectroscopy. Incorporation of different inorganic nanoparticles and polymer molecules allows control over electromagnetic, mechanical, thermal and other properties.
