In this study, it was aimed to synthesize and characterize cellulose based silica carbon aerogel by solgel method. Pooled and hand-peeled hemp fibers were used as the source of cellulose at the time of
October-2018 harvest in Vezir Köprü, Samsun province. Hemp fiber containing crude cellulose was
mechanically made into cellulose pulp. Then, Silica aerogel (SA) sample was synthesized by Sol-gel
method and subsequent freeze-drying process. Finally, the synthesized SA sample was kept in a tube
oven at a heating rate of 5 oC/min under a nitrogen flow of 120 ml/min for 2 hours at 500 oC to obtain
cellulose-based carbon aerogel (SCA). Synthesized samples; Scanning Electron Microscopy (SEM),
Energy dispersive spectrometer (EDS), Surface analysis measurement (BET), Fourier transform infrared
spectroscopy (FTIR), X-ray diffraction method (XRD) and electrical conductivity analyzes were
performed. As a result of electrical conductivity analysis, the electrical resistances of the silica aerojels
was found to be very high. It was interpreted that the synthesized samples could be used as an insulator.
