In this work, two types of paper (uncoated paper and a highly porous air filter paper) were used in order to test micro-structured cellulose from soy hulls as coating additives. These samples were isolated from soybean hulls by combining chemical and mechanical treatments. Measurements of porosity, roughness, and air permeability, among others, were used in order to evaluate the coating process. The results indicate a significant reduction on the air permeability of the paper samples after coating with given formulations of the soy hulls cellulose, and indication that these low costs material from widely available residual bioresource can be used for high performance applications such as paper coating processes.
