Structural studies of mechanical printing paper coating using SEM

In this study, surface coating of mechanical printing paper was carried out by precipitated calcium carbonate (PCC) and Nanoclay. Specimens viewed using a conventional scanning electron microscope (SEM) need to be coated with electrically conductive material before generation high-resolution images. The structural images of SEM from fiber net status and mineral coating showed that PCC led to greater uniformity of the paper surface than using Nanoparticles. The result revealed that it is possible application up to 50 percent of the minerals for coating of printing paper.
