The surface force profiles between an atomic force microscopy (AFM) tip and a self-assembled monolayer of noctadecyltrichlorosilane on oxidized silicon were measured in an ABA triblock series of silicone and Pluronic surfactant solutions. Changes in steric force barrier thickness and height were examined as a function of hydrophobic and hydrophilic block… (More)
