Synthesis of silver graphene oxide nanocomposite reinforced with kenaf cellulose nanofibril aerogel

Abstract

A facile synthesis of silver graphene oxide and kenaf cellulose nanofibril (GOAg-CNF) nanocomposite aerogel is reported in this work. The nanocomposite has been characterized using UV-Visible spectroscopy, X-ray diffraction (XRD), Fourier-transform Infrared Spectroscopy (FTIR), Field Emission Scanning electron microscopy (FESEM) and Transmission Electron microscopy (TEM). The objective of this study is to synthesis highly homogenous silver nanoparticle on graphene oxide layer and creating hybrid material in combination with cellulose nanofibril aerogel. GOAg has been synthesized using microwave irradiation method and cellulose nanofibril has been synthesized by bleaching method followed by mechanical disintegration (ultrasonication). The characterization of GOAg-CNF electron microscopy shows the formation of highly homogeneous nanocomposite where the AgNPs are properly distributed on GO and CNF. The average size of AgNPs and CNF obtained is 10 ± 1.9 nm and 14 nm. Subsequently, a mixture of GOAg and kenaf cellulose nanofibril shows very promising properties for future application such as in antibacterial study, water treatment and wound dressing.A facile synthesis of silver graphene oxide and kenaf cellulose nanofibril (GOAg-CNF) nanocomposite aerogel is reported in this work.
