Pure and $${\hbox {Cu}}^{2+}$$ Cu 2 + doped methacrylic acid–ethyl acrylate (MAA:EA) copolymer films were prepared using the solution cast technique. The amorphous feature of the copolymer was depicted using X-ray diffraction scans and degree of crystallinity was found to vary with increasing doping content. UV–Vis absorption spectra in the wavelength region 200–900 nm were used to...
