Abstract

Cellulose nanocrystals (CNCs) are a very versatile material, and optimizing the reaction conditions to obtain them is vital for cost savings, purity, selectivity, or performance. In this study, the reaction conditions of the CNCs were tested, as well as their application as binders for the fabrication of electrodes of a symmetric capacitor (based on activated carbon). The resulting CNCs were physicochemically characterized using Fourier transform infrared spectroscopy, thermogravimetric analysis, X-ray diffraction, atomic force microscopy, and its capacitive properties using cyclic voltammetry (CV). It was found that the best reaction conditions were at 45°C, 30 and 45 minutes, and 64 wt%. The CNCs were used as a binder, as they conferred stability to the electrodes and prevented the crumbling of the activated carbon electrodes. The CV measurements showed a capacitor behavior; CNCs can be used in energy storage applications.

纤维素纳米晶体作为电容器粘结剂的合成参数优化及应用

纤维素纳米晶体（CNCs）是一种用途广泛的材料，优化获得它们的反应条件对节约成本、纯度、选择性或性能至关重要。在本研究中，测试了CNCs的反应条件，以及它们作为粘合剂在制造对称电容器（基于活性炭）电极中的应用。使用傅里叶变换红外光谱、热重分析、X射线衍射、原子力显微镜对所得CNCs进行物理化学表征，并使用循环伏安法（CV）对其电容特性进行表征。研究发现，最佳反应条件为45°C，30和45分钟，64 重量%。CNCs被用作粘合剂，因为它们赋予电极稳定性并防止活性炭电极的碎裂。CV测量显示电容器行为；CNCs可用于储能应用。
