Promising naphthol green B dye doped (PVOH-PEG) composite films as a multifunctional material with engineered optical band gap, tunable dielectric properties and nonlinear J–E characteristics
Abstract
Polymer composite films of polyvinyl alcohol (PVOH)—polyethylene glycol (PEG)/naphthol green B dye (NGB) were prepared using the solution cast technique with different concentrations of NGB (0–25 wt. (%)). XRD emphasized the semi-crystalline nature of the base polymer blend (PVOH-PEG) which increased by NGB addition. FTIR spectra of the investigated samples confirmed the formation of hydrogen bonds between the polymer blend hydroxyl groups and the NGB molecules. Optical properties are studied within wavelengths ranged from 245 nm to 1500 nm.
