In order to better understand the formation mechanism of
RGO@CNC/NR nanocomposites with 3D conductive network, the
entire experimental process is schematically illustrated in Fig. 1.
CNC were derived from cellulose by the controlled acid hydrolysis
of cotton fibers. When GO was added into the CNC suspensions
under magnetic stirring, amphiphilic CNC could self-assemble on
the surface of GO nanosheets due to the interfacial interaction
between hydroxyl groups of CNC and oxygen-containing groups
