【 摘 要 】

Bamboo is one the important bioresources under the tropical climate. It has high growth efficiency with a low cost between other lignocellulosic resources. It has become important to produce nanocelulose with the right methods and from economical sources that reveal its potential with its high mechanical strength, biocompatibility in the areas such as composites or pharmaceuticals. Cellulose nanofibers were obtained at an observable minimal of 200 nm by the sulfuric acid method of Forgesia nitida bamboo. First, bamboo was soxlet extrated with cyclohexane (2:1) ethanol for 12 hours to dissolve and remove the leachate and waxy materials. Then 8% of potassium hydroxide was used for alkaline treatment. The solid was neutralized with 10% acetic acid solution. Then, re-bleaching with sodium chloride was applied according to TAPPI method. Cellulose nanofibrils were produced by refluxing at 60°C for 2 hours with 6.5 M sulfuric acid solution. Chemical properties of nanofibrils were investigated by FTIR spectroscopy, thermal properties TGA-DTG analysis, light microscopy with morphological characteristics.
