Abstract:In this work, the degradation evolution of curauá fiber, subjected to acid hydrolysis, was monitored at different times. It was observed that the hydrolysis is initiated by a fibrilation process, allowing the access of acid throughout the fiber structure. The cross-section micrographs of the embedded fibers suggested that the acid attack in plant cells takes place towards the middle lamella to the inner regions of the cell wall. Exposure of nanocrystals that attached to the cell wall, as well as, clusters of i… Show more
