The data shown in this document provides all the experimental data that complement the article published in Carbohydrate Polymers entitled "Influence of operating conditions on Proton Conductivity of Nanocellulose films using two Agroindustrial Wastes: Sugarcane Bagasse and Pinewood Sawdust" [1]. The data of this paper are the result of a large series of experiments to optimize the extraction of cellulose nanocrystalline (CNC) from these two agro-industrial wastes: sugarcane Bagasse (SCB) and pinewood sawdust (PSW). The conditions of pretreatment (5 wt.% or 10 wt.% of NaOH) and hydrolysis temperature (60, 75 and 90°C) in an aqueous solution of 45 wt.% of HSO were analyzed exhaustively. The data includes the characterization by Fourier transform infrared (FT-IR), Differential Scanning Calorimetry/Thermogravimetric Analysis (DSC/TGA), Dynamic Light Scattering (DLS), X-ray diffraction (XRD) patterns, Scanning Electron Microscopy (SEM), Transmission Electron Microscopy (TEM) micrographs with their corresponding SAED patterns and nanoindentation tests. Additionally, photographs during the isolation of cellulose nanocrystalline in dependence of the syntheses parameters. It is also included the data that complement the molecular dynamic simulation generated by GLYCAM carbohydrate builder based on the coordinates for alpha and beta cellulose considering a microfibril of 5, 10 and 20 glucosyl residues (degree of polymerization, DP). Overall data have not been previously published and are available contributing to a better understanding of the CNCs isolation through different pretreatment concentrations and temperatures of processing.
本文档中所示的数据提供了所有实验数据，这些数据补充了发表在《碳水化合物聚合物》上的一篇文章，题为“使用两种农业工业废料：甘蔗渣和松木锯末，操作条件对纳米纤维素膜质子传导率的影响”[1]。本文的数据是一系列大量实验的结果，这些实验旨在优化从这两种农业工业废料：甘蔗渣（SCB）和松木锯末（PSW）中提取纤维素纳米晶体（CNC）的工艺。详尽分析了在45 wt.% 的HSO水溶液中的预处理条件（5 wt.% 或10 wt.% 的NaOH）和水解温度（60、75和90°C）。数据包括通过傅里叶变换红外光谱（FT-IR）、差示扫描量热法/热重分析（DSC/TGA）、动态光散射（DLS）、X射线衍射（XRD）图谱、扫描电子显微镜（SEM）、透射电子显微镜（TEM）显微照片及其相应的选区电子衍射（SAED）图谱以及纳米压痕测试进行的表征。此外，还有根据合成参数在分离纤维素纳米晶体过程中的照片。还包括补充基于GLYCAM碳水化合物构建器生成的分子动力学模拟的数据，该模拟基于考虑了5、10和20个葡萄糖基残基（聚合度，DP）的微纤丝的α和β纤维素坐标。总体数据此前未曾发表，其可得性有助于更好地理解通过不同预处理浓度和加工温度分离CNC的过程。
