Obtenção de nanowhiskers a partir de fibras de bambu para uso em nanocompósitos

Abstract

Bamboo fibers are rich in cellulose, hemicellulose and lignin. They present high elastic modulus and high mechanical strength, which makes them very effective as reinforcement in composites. In order to improve the mechanical properties of polymeric materials in very small scales, the application of these reinforcements in their nano form has been investigated. The nanocellulose extraction has been studied a lot and, in our work, adjustments in some methods that showed to be more effective were done. The nanowhiskers made from bamboo was obtained by 64% of acid hydrolisis after prior chemical treatment of cleaning and bleaching. The materials were then characterized by FTIR, TG, DTG and particle size by Zeta Pontential, which indicated that the production method was effective.
