Impact of MWCNTs on the structural, electrical, and optical characteristics of PVA/PANi blends

open access: yesJournal of Taibah University for Science, 2023
Polyvinyl alcohol (PVA)/0.25% polyaniline (PANi)/x wt % MWCNTs (x = 0, 0.1, 0.2, 0.5, 0.8, 1) blends were formed. The X-ray diffraction technique was used to investigate the formation of the different blends.
