Abstract

Molecularly-ordered thin-films comprised of nanosized 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 fabricated up to several hundred layers in thickness and characterized by UV-vis spectroscopy. Incorporation of different nanoparticles and polymer molecules allows tailoring of physical properties.
