DGEBA epoxy polymer composite panels (MB: DGEBA-EPCPs): structural, optical, and dielectric properties-leanings and appliances in optical electronics

Pure DGEBA epoxy polymer (DGEBA-EP) and MB: DGEBA-EPCPs with different MB dye contents were made using a basic casting suspension system. The enhancing effect of MB organic dye doping on the structural, optical, and dielectric properties has been investigated. The spectra XRD analysis shows an amorphous crystalline peak of approximately 2θ^∘ =18^∘ explaining the pure DGEBA-EP matrix semi-crystalline structure. No XRD-related trends peak related to MB atoms shows a high level of polymer mixture formation free from crystalline MB atoms and total miscibility of MB dye in the DGEBA-EP matrix. Since indirect band gaps are decreasing, light absorption behavior is improved, making the panels suitable for optical laser filter tools. A complete UV–Vis’s blocking in wavelength at 675 nm for the high levels of MB organic dye has been enhanced by limiting effect measurements of the MB: DGEBA-EPCPs. Our dielectric parameters pronounced that the MB organic dye is a respectable filler to enhance the electrical AC conductivity of the MB: DGEBA-EPCPs materials.
