我们提出了当聚合物通过挥发性溶剂蒸发而沉积在孔中时，测量的圆柱形孔的孔径分布变化的三个模型。预测结果有助于解释多孔氧化锆上聚丁二烯 (PBD) 涂层的实验氮吸附数据。在低负载下，PBD 似乎在表面沉积薄层，不优先填充大孔或小孔。在较高的 PBD 负载量下，聚合物优先沉积在较小的孔隙中。这与多孔二氧化硅上的 PBD 涂层定性一致。
We present three models of the changes in measured pore size distribution for cylindrical pores when a polymer is deposited in the pores by evaporation from a volatile solvent. The predicted results serve as an aid in interpreting experimental nitrogen adsorption data for polybutadiene (PBD) coatings on porous zirconia. At low loadings, PBD appears to deposit in thin layers on the surface with no preference for filling either large or small pores. At higher PBD loadings, the polymer deposits preferentially in smaller pores. This is in qualitative agreement with PBD coatings on porous silica.
