Mh. Chen et K. Furusawa, A NOVEL EVALUATION METHOD FOR THE ADSORPTION ENERGY OF TERMINALLY ADSORBED POLYMER, Chemistry Letters, (12), 1996, pp. 1019-1020
Using a new experimental technique, ''continuous elution method'', pol
ystyrene (PS-X) functionalized by a terminal iminium ion(X) was found
forming a terminally adsorbed polymer layer on alpha-Al2O3 surface. Ba
sed on the balance between adsorption and desorption, the adsorption e
nergy of the terminally adsorbed polymer was evaluated to be 4.2 simil
ar to 4.3 kT with regarding to the osmotic pressure as a desorption fo
rce.
