Interaction force between solid surfaces in aqueous solvent was investigated using scanning probe microscopy Only short-range repulsive forces were observed in a poly(ammonium acrylate) (PAA) solution Their range increased concomitantly with Increase of the molecular weight of the PAA In a PAA solution with 0 1-1 mM KCl, the PAA adsorbed onto the Si substrate Furthermore, the interaction force was described by DLVO theory, and repulsive force is thought to originate from the steric hindrance of the PAA
