Abstract
The present study evaluated the possibility to form thin film of cationic guar gum (CGG) associated with poly (carboxylic acid) such as carboxymethyl cellulose (CMC) and poly (acrylic acid) (PAA) through layer-by-layer (LbL) assembly. The thin film thickness and morphology show dependence on pH value, ionic strength and temperature. For pH 3 to pH 4 CGG and poly (carboxylic acids) assemble and form thin film through LbL. For neutral pH region and high pH values CGG and poly (carboxylic acids) do not interacted. In contrast to synthetic polyelectrolyte complex thin film, such as polystyrene sulfonate (PSS)/ poly (diallyldimethylammonium chloride) (PDDA) and PSS/ poly (allylamine hydrochloride) (PAH), the LbL assembly of CGG/CMC and CGG/PAA take place only at low salt concentrations. Deposition at high temperature (up to 60°C) results thicker CGG/ poly (carboxylic acids) films.
