Polarized light reflectometry for studies of paper coating structure Part II. Application to coating structure, gloss and porosity.

The article presents a study about the use of use polarized light reflectometry technique in analyzing a wide-scale of coated papers from pulp mills in the U.S. The polarized light reflectometry technique measures roughness and refractive index of the surface which can help in examining the surface porosity properties. The study aims to show how the technique can provide information about surface porosity, composition, and structure. The study reveals that the technique is useful for investigating of the coating structure and explains the source of gloss. However, the technique needs further applications and materials to be studied to examine its consistency.
