Synthesis and characterization of Cu(II) containing PMMA co-polymer for optical applications

Abstract

Homogenous, transparent, greenish blue Cu(II) containing PMMA co-polymer disks were prepared through the radical polymerization of the Cu(II) methac rylate, MMA and HMA using AIBN as an initiator. The dependence of the absorbance and transmittance spectra with the Cu(II) methacrylate concentration was investi gated in the visible range (420–750 nm). From the trans mittance measurements the refractive index and extinction coefficient spectral dependence were calculated by appli cation of an inversion approach. To further characterize this co-polymer a thermogram was performed. The overall behavior of this material suggests its possible use as a standard solution for Spectroscopy Equipment Calibration and as a selective optical filter.
