| 摘 要： | 该文介绍了用AFM观测颜料涂布纸涂层Z向结构的方法。颜料主要是粒径大小和分布范围不同的PCC和kaolin。对于kaolin颜料,粒径大小与涂层孔隙的大小一致。粒径分布范围与孔隙体积成反比。PCC颜料可以在涂层中产生更多的细小孔隙。

| Abstract: | A method had been developed for characterizing the z-directional pore structure of paper coatings with atomic force microscopy(AFM).The method was used to analyze cross sections of samples coated with kaolin and precipitated calcium carbonate(PCC)pigments of various particle sizes and particle size distributions.For kaolin,the median size of pigment particles correlated with the average pore size of the coating pore volume.Compared to kaolin clays of similar median particle size,the PCC pigment gave more pores per unit mass and a smaller average pore size. |
