生物质废弃物制纳米纤维素及电化学应用研究

Preparation of Nano-cellulose from Biomass Waste and Its Electrochemical Application

纳米纤维素是一种具有独特结构、良好力学性能、高比表面积的新型纳米材料,与其它纳米材料不同之处在于其可来源于生物质材料。近年来的研究表明,利用生物质废弃物能制备出质量较好的纳米纤维素,并且该类纤维素可在锂离子电池、超级电容器和传感器等电化学领域进行应用,特别是在便携式电子器件和柔性电子装置的开发上有广阔的应用前景;但利用生物质废弃物制备纳米纤维素还需要优化制备方法,进一步提高纤维素结构的稳定性,以实现生物质废弃物的高值化利用。

Nanocellulose is a new type of nanomaterial with a unique structure,good mechanical properties,and high specific surface area.One of its difference from other nanomaterials is that it can be obtained from biomass waste.Recent studies have shown that the use of biomass waste can produce better quality nanocellulose.Moreover,this type of cellulose can be applied in electrochemical fields such as lithium-ion batteries,supercapacitors and sensors.It has broad application prospects especially in the development of portable electronic devices and flexible electronic devices.However,preparation method for biomass waste for obtaining nano-cellulose still needs optimization to further improve the stability of the cellulose structure in order to realize the high-value utilization of biomass waste.
