“…8c, values of EU are estimated and demonstrated in Table 4. It is evident that increasing the concentration of NiCl2 in the ABS matrix increased the Urbach energy from 1.17 eV of pure ABS to 5.00 eV for ABS/15 wt% NiCl2, indicating that the disorder has been increased in the composite samples [Habib et al 2022;Fahmy et al 2022]. This change in the Urbach energy values is a consequence of the defects in the ABS main chain after the addition of NiCl2.…”

Acrylonitrile-butadiene-styrene/nickel chloride (ABS/NiCl2) composites are prepared using the casting method. Structure of these composites is investigated by XRD and FTIR spectroscopy. XRD measurements revealed that the structural properties of ABS host polymer have been modified after doping with NiCl2. Various structural parameters such as crystallite size (D), lattice strain (ε) and dislocation density (δ) are estimated. ATR-FTIR spectra exhibited a clear change in the intensity and position of some of the main bands of the ABS polymer such as, Ni(OH)2, C ≡ N, C = O and C = C which confirms the interaction between ABS terpolymer and NiCl2. Coats–Redfern approach has been applied to explore the effect of NiCl2 on the kinetics of thermal degradation of pure ABS and ABS/NiCl2 composites. The results showed that the activation energy of every thermal degradation stage increases with increasing NiCl2 content confirming that the thermal stability of ABS/NiCl2 composites has been enhanced. The optical parameters such as Urbach energy (EU) and bandgap energy (Eg) are investigated in terms of the absorption coefficient. The dispersion parameters such as, oscillator energy (E0), dispersion energy (Ed), transition moments (M− 1 and M− 3) and oscillator strength (f) are evaluated by applying the single oscillator model (SOM). Effect of NiCl2 on the linear/nonlinear optical (NLO) parameters is investigated. Our results clearly revealed that doping ABS with NiCl2 improved the nonlinear optical properties, which are preferred for optoelectronic device applications.

Poly(vinylidene fluoride-co-hexafluoropropylene) P(VDF-HFP) doped with 4-N,N-dimethylamino-4-N-methyl-stilbazolium tosylate (DAST) composites with various concentrations of DAST dye is prepared using the casting method. The crystal structure and optical properties of the pure and P(VDF-HFP)/DAST composites with various contents of DAST dye are investigated using various techniques such as UV–Vis spectroscopy, X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FTIR) and polarized optical microscopy (POM). The analysis of XRD data and FTIR spectra revealed that the β-fraction has been improved in the composite samples with increasing the content of DAST dye. Analysis of UV spectra displayed that the optical band gap of P(VDF-HFP) pure copolymer is 5.41 eV and has been reduced to be 3.75 eV for P(VDF-HFP)/10 wt% DAST that will be suitable for efficient systems of energy conversion and multijunction-based layer solar cells. Also, it is found that the nonlinear and linear optical parameters of the composite samples are DAST dye-dependent. Thermally stimulated depolarization current (TSDC) technique has been applied to investigate the dipolar and space charge relaxations of the composites. Moreover, it is observed that the pyroelectricity and piezoelectricity are enhanced with increasing the content of DAST dye. The highest content of the DAST dye showed maximum values of the pyroelectric and the piezoelectric coefficients of ~ 4 × 10–5 C/m2 K and ~ 34 pC/N at stress of 6.27 × 105 Pa, respectively. Our results of the polymer/dye composites give an opportunity of a promising material for flexible piezoelectricity devices used in many potential applications and energy harvesting systems.
