高分子在固体表面上的吸附层厚度对了解其结构具有重要意义．厚度的测量通常采用椭圆偏振法、流体力学法和沉降法等几种方法来测量［１］．流体力学法始创于５０年代中期Ｏｈｒｎ［２］对极稀高分子溶液粘度异常行为的解释．由于高分子在粘度计的毛细管管壁上的吸附，致使... Polymer adsorption layer thickness on the solid surface of understanding its structure is of great significance. Thickness measurements are usually measured by ellipsometry, fluid mechanics and sedimentation methods [1]. The hydrodynamic method was first introduced in the mid-1950s by Ohrn [2] to explain the abnormal viscosity behavior of very dilute polymer solutions. As the polymer in the viscometer capillary tube wall adsorption, resulting in ...
