【摘要】 利用小角X射线散射技术研究了吸附剂的孔结构。选择含6％二乙烯基苯和100％汽油作致孔剂制备的干燥及水和甲苯溶胀的聚合物小球为样品,测定了干态及溶胀态样品的平均孔径及孔径分布。得到了随溶剂吸附量增加平均孔径变化的关系。对吸附和溶胀机理作了初步探讨。更多还原

【Abstract】 The small-angle X-ray scattering (SAXS) technique was applied for the study of the pore structure of Polymeric adsorbents. This paper relates the principle, experimental, procedure and requirements and the experimental results from dry and wet swollen Leads of polymeric adsorbents. The sample 6×100, which was prepared with 6% of divinylbenzene and 100% of petrol as porogenic agent were investigated with the above mentioned instrument in order to find out their average pore diameters and pore distribution under the swollen condition. The relation of the change of average pore diameter as the increase of adsorption of solvent was obtained. The adsorption and swollen mechanism were discussed.更多还原
