A chemi-mechanical approach was used to extract cellulose nanofibres (CNFs) from waste mango wood scraps using a mild chemical treatment ensuring no acid hydrolysis. The dimensional analysis for CNFs has been done by taking into account both the microscopic and light scattering techniques. The FESEM (field emission scanning electron microscopy) analysis revealed the diameter of obtained CNFs in the range of 5-40nm with an average diameter of approximately 12nm. The AFM (atomic force microscopy) analysis gave a more precise average diameter value of 5nm for the obtained CNFs. The aspect ratio as determined by applying mathematical calculations on the data revealed through dynamic and static light scattering techniques (DLS, SLS) was approximately 200. The characteristic shape determined by fractal dimension investigation from SLS measurement revealed the rod/thread like shape of CNFs at lower concentrations.
采用化学机械法从废弃芒果木屑中提取纤维素纳米纤维（CNF），采用温和的化学处理确保没有酸水解。通过考虑微观和光散射技术，对 CNF 的尺寸分析进行了处理。FESEM（场发射扫描电子显微镜）分析表明，所得到的 CNF 的直径在 5-40nm 范围内，平均直径约为 12nm。AFM（原子力显微镜）分析给出了更精确的平均直径值，即 5nm。通过对动态和静态光散射技术（DLS、SLS）获得的数据进行数学计算确定的纵横比约为 200。通过 SLS 测量的分形维数研究确定的特征形状表明，在较低浓度下，CNF 呈棒/线状。
