Cellulose nanoparticles (CNs) were prepared by acid hydrolysis of the cellulose pulp extracted from the Brazilian satintail (Imperata Brasiliensis) plant using a conventional and a total chlorine free method. Initially, a statistical design of experiment was carried out using Taguchi orthogonal array to study the hydrolysis parameters, and the main properties (crystallinity, thermal stability, morphology, and sizes) of the nanocellulose. X-ray diffraction (XRD), fourier-transform infrared spectroscopy (FTIR), field-emission scanning electron microscopy (FE-SEM), dynamic light scattering (DLS), zeta potential and thermogravimetric analysis (TGA) were carried out to characterize the physical-chemical properties of the CNs obtained. Cellulose nanoparticles with diameter ranging from 10 to 60 nm and length between 150–250 nm were successfully obtained at sulfuric acid concentration of 64% (m/m), temperature 35 °C, reaction time 75 min, and a 1:20 (g/mL) pulp-to-solution ratio. Under this condition, the Imperata Brasiliensis CNs showed good stability in suspension, crystallinity index of 65%, and a cellulose degradation temperature of about 117 °C. Considering that these properties are similar to those of nanocelluloses from other lignocellulosics feedstocks, Imperata grass seems also to be a suitable source for nanocellulose production.

纤维素纳米颗粒（CNs）是通过酸水解从巴西绸缎（Imperata Brasiliensis）中提取的纤维素纸浆而制备的）工厂采用常规的完全无氯的方法。最初，使用Taguchi正交阵列进行实验的统计设计，以研究水解参数以及纳米纤维素的主要特性（结晶度，热稳定性，形态和尺寸）。进行了X射线衍射（XRD），傅立叶变换红外光谱（FTIR），场发射扫描电子显微镜（FE-SEM），动态光散射（DLS），ζ电位和热重分析（TGA）的表征。获得的氯化萘的物理化学性质。在硫酸浓度为64％（m / m），温度为35°C，反应时间为75分钟和1:20（g / mL）纸浆与溶液的比例。巴西白茅CNs在悬浮液中显示出良好的稳定性，结晶度为65％，纤维素降解温度约为117°C。考虑到这些性质类似于来自其他木质纤维素原料的纳米纤维素的性质，Imperata草似乎也是适合生产纳米纤维素的来源。
