Nanocellulose fibers with the average diameter below 100nm were successfully obtained by a high shear microfluidizer. Their large surface area and nano-scale dimensions can lead to the emerging materials for reinforcements in polymer composites, differentiating from common polymer composites and providing the opportunity for nano-engineered materials that could have not achieved from conventional materials. Enormous amount of hydroxyl groups, covered on the surface of nanocellulose, could often be a drawback as a reinforcement in hydrophobic polymeric matrix. Silanization have been a well-known technology to modify the surface of the reinforcement with a compatibility. The wet-laid process was found a good method to make nanocellulose/Polyamide 6 nanocomposites. Their mechanical properties were increased due to the treatment with silane on the surface of nanocellulose compared with non-treated original nanocellulose.
