Abstract
Influence of polymer additive and surface roughness on liquid transfer phenomena was investigated utilizing two flat plates. Test fluids of water or polymer (PEO, SPA) aqueous solutions were transferred from an acrylic plate to aluminum plates with different surface roughness. In the cases with rough surface, similar transfer ratios were obtained regardless of test fluids, i.e. Newtonian or polymer solutions. On the other hand, only the PEO solution keeps higher transfer ratio even when relatively smooth surface was utilized, and water and the SPA solution were slightly transferred to the aluminum plate. In order to verify the effect of molecular weight to the transfer phenomena with relatively smooth surface, an aqueous solution of PEG having same molecular chain structure with the PEO was also examined. But short chain of polymer (PEG) additive did not show such kind of advantage in transfer phenomena.
