A Novel Evaluation Method for the Adsorption Energy of Terminally Adsorbed Polymer.
Using a new experimental technique, “continuous elution method”, polystyrene (PS-X) functionalized by a terminal iminium ion(X) was found forming a terminally adsorbed polymer layer on α-Al2O3 surface. Based on the balance between adsorption and desorption, the adsorption energy of the terminally adsorbed polymer was evaluated to be 4.2∼4.3 kT with regarding to the osmotic pressure as a desorption force.
