As an alternative biomass, the giant miscanthus was introduced for raising the bio industry in Korea. Unlike the expectations, however, its application has been limited due to its low economical value. To utilize it as a high added value material, in this study, the feasibility of nanofiber production from giant miscanthus holocellulose treated with delignification by peracetic acid method and their properties were investigated. The yield of the cellulose nanofiber produced by the acid hydrolysis method using sulfuric acid was calculated on the base of percentage of moisture content of the obtained suspension. As results, the yields were affected by sulfuric acid concentration, reaction time and temperature. The higher the reaction temperature, the smaller the length and width of the fiber were observed by TEM analysis. In addition, TEMPO oxidized giant miscanthus cellulose fiber treated with ball mill was shorter in fiber length than that of by homogenizer treatment. Moreover, the particle size was manufactured with uniform size with increase of the ball mill and homogenizer processing speed and time. In the FT-IR analysis, the carboxylation reaction of cellulose was confirmed. It was confirmed by X-ray diffraction analysis that the intensity of 002 was shifted after the ball mill and homogenizer treatment of TEMPO oxidized giant miscanthus cellulose.
