A novel rigid-rod polymer, 2,9,16,23-tetra-tetradecanophthalocyaninato polysiloxane and its precursor dihydroxo(2,9,16,23-tetra-tetradecanophthalocyaninato) silicium were prepared. The monolayer behaviors of the compounds at the air-water interface are investigated by means of in situ Brewster angle microscopy and their corresponding π-A isotherms. The LB films of the compounds are deposited by a...
From the experimental results using the 'continuous elusion method', the adsorption energy of end-functionalized polymer (PS-X) has been analyzed. It was found that PS-X forms a terminally adsorbed polymer layer on α-Al 2 O 3 surface packed closely with each other, and that the adsorption force is balanced with the desorption force which is contributed from the osmotic pressure in...
A new analytical method for studying polymer adsorption/desorption, which is termed the “continuous elution method”, has been developed. In this method, preadsorbed adsorbent powders are packed into a small column, solvent elution is performed and the concentration of polymer desorbed from the adsorbent surface is measured. By this method, the adsorption/desorption behavior of polystyrene on/from...
