摘要

根据仿生棉花“轻柔飘逸”的特性,制备了具有超轻、超疏水、弹性和可折叠性能的一种新型纳米纤丝化纤维素(NFC)气凝胶。将废弃的枯落竹叶通过一系列化学处理,获得纯化的枯落竹叶纤维素。纤维素通过超声处理,可以将纤维素束分散成纳米纤维素纤维,经过冷冻干燥,制备NFC气凝胶。再通过MTMS处理,制备出具有这些性能的NFC气凝胶。采用接触角测量仪测得接触角为152°。通过扫描电子显微镜(SEM)和能量弥散X射线分析(EDS)对纯化的纤维素和制备的气凝胶的表面形貌和能谱进行分析,通过傅里叶变换红外光谱(FT-IR)对枯落竹叶、纯化后的纤维素和获得的气凝胶进行官能团分析。该研究所用试剂均为绿色环保,为绿色气凝胶的制备提供了科学思路。

Abstract

In order to achieve the characteristics of "Light-Soft-Floating-Flexible" of cotton through bionics, the novel nanofibrillar cellulose(NFC) aerogels with ultralight, superhydrophobic, elastic and collapsible properties are prepared. The dropped bamboo leaves(DBL) go through a series of chemical treatments to obtain the purified cellulose, and then through the ultrasonic treatment to turn the disassembly bundled cellulose to the NFC. A nanolayer of the methyltrimethoxysilane is covered to the surface of the NFC aerogels to fabricate the superhydrophobic aerogels. The contact angle measurement, the scanning electron microscopy(SEM), the Fourier transform infrared spectroscopy(FTIR), and the energy dispersive X-ray spectroscopy(EDS) are employed to characterize the features of the asprepared aerogels. This paper provides a feasible route for the fabrication of the novel natural nanofibers from waste biomass.
