In order to check the presence of covalent bonds between the cellulose chains and the MWCNTs, the RC-MWCNT paper was investigated by Fourier transform infrared FT-IR spectrometer Bruker, VERTEX 80v and Raman spectrophotometer Bruker, RFS 100/S with excitation source yttrium aluminum garnet laser, =1064 nm using the laser power of 130 mW.
