ABSTRACT Using nanostructured materials issued from renewable resources could be the key to the development of good-quality low-cost products that help reduce pollution. Cellulose nanofbrils (CNFs) were obtained by alkaline and bleaching treatments of Amazonian Paricá hardwood sawdust, a waste material from the Brazilian forestry industry. This study evaluated a process consisting in alternating layers of Paricá CNFs and cassava starch to coat standard writing and printing (W&P) papers with a skim-coating method, in which one face of each paper sample is passed over the surface of a suspension containing either CNFs or cassava starch, alternatively. The coated samples were then compared to the uncoated paper in terms of mechanical and surface properties. The mechanical properties of the papers coated with alkaline CNFs showed a declining trend as the number of coating layers increased (from 47 to 31 MPa). The papers coated with starch layers showed improved mechanical performance compared to the samples only coated with alkaline and alkaline bleached CNFs. All the coated samples showed excellent resistance to water degradation. The worst degradation (4%) was observed for the samples coated with a single layer of alkaline CNFs. A signifcant improvement in surface wetability was observed when gelatinized cassava starch was applied to the paper samples, irrespective of the type of CNFs eventually present on the surface. All in all, these results suggest that using gelatinized cassava starch as an alternating layer between successive CNFs layers on the surface of W&P paper samples may be promising for improving their overall properties.
