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.
