Adsorption Study of The Polymer on a Metallic Surface With ATR Method

This paper uses Attenuated Total Reflection methods （ATR） to study adsorption of polymer on a metallic surface. Adsorption of polystyrent in various solution on Ag surface was measured. We get adsorption change law with time, adsorptional thickness d and dielectric constants Re∈, Im∈. The result demonstrates that adsorbance of the polymer increases with adsorption time and mol. wt. and that absorbance of not good solvate are more than good solvate. Adsorptional process accords with Langmuir equation. The experimental methods can applied.any solutions and also scattering solutions.
