Abstract: Nanotechnology is prominent in several key areas, ranging from medicine to electronics. For papermaking, it is no different. Opposite charged polyelectrolytes adsorbed by lignocellulose fibres – nanolayers, gave birth to a new papermaking process, conferring improved physical properties from tensile strength to burst strength. New properties are also implied like conductivity and interactivity. Its industrialisation is a step forward. The present work has the objective to show how to industrialise a simple, precise deposition nanolayer adsorption over the lignocellulose substrate improving up to two times its dry strength using biopolymers, which compose the polyelectrolyte used.

Keywords: layer-by-layer; nanotechnology; nanoassembly; lignocellulose fibers; papermaking; nanolayers; deposition nanolayer adsorption; polyelectrolytes; biopolymers.
