Investigating the Impact of Doping Ratios on the Optical Features of Poly (Methyl Methacrylate)

Abstract

Using spin-coating method, the poly (methyl methacrylate) (PMMA)/multi-walled carbon nanotubes (MWCNTs) thin films are prepared. The optical features from the band gap, refractive index and optical connectivity are studied. The gap was calculated from the UV-Vis spectra. The superficial structure is examined through the use of the atomic force microscope (AFM) to investigate the dispersion of MWCNT within the polymer matrix.
