Abstract
Vibrationally resonant sum frequency generation (VR-SFG) is used to determine the structure of the phenyl side groups of deuterated polystyrene at the liquid/solid interface for the nonsolvent liquids: hexane, methanol, ethanol, glycerol, and water. The structure for the three low surface tension (g) liquids: hexane, methanol, and ethanol is similar and only slightly perturbed from that of the air/solid interface. The air interface is highly ordered with the phenyl rings oriented away from the polymer bulk. The low g interfaces are very similar to the air interface. The structure for the two high g liquids: water and glycerol, is similar and reflects a near flat orientation of the phenyl ring.Citation
