ニ成分系添加剤の吸着挙動および吸着膜の特性の測定

In order to elucidate the competitive adsorption phenomenon of two-component system of oiliness agents, the adsorption behavior and the mechanical properties of adsorption films were examined by using QCM-D and AFM. Stearic acid (SA) and oleic acid (OA) were used as oiliness additives. The results of AFM indicated that the two-component adsorption films of LB film and SAM both consisted of three regions of SA region, OA region, and mixed region, which were structured hierarchically in nano-micro scale. The results of QCM-D indicated that the adsorption amount of the two-component solution was larger than that of the single-component solutions.
