β-Phase Cu-Phthalocyanine/Acrylonitrile Butadiene Styrene Terpolymer Nanocomposite Film Technology for Organoelectronic Applications

To investigate electronic properties, such as dielectric permittivity, dielectric loss, conductivity, capacitance, and Nyquist plots, acrylonitrile butadiene styrene (ABS) and β-CuPc (10–40 wt % of β-CuPc) formulation was utilized to fabricate nanocomposite films via the cost-effective solution processing technique. Cross-sectional morphological investigations were performed for the developed composites with the aid of Field emission scanning electron microscopy microscopy; the result suggested that the modified cross-sectional surface morphology was due to the addition of the β-CuPc compound. Further, the interactions-attributable phase groups of the polymer with the β-CuPc compound were studied by Fourier-transform infrared spectroscopy. The UV–vis spectroscopy result suggested that the absorption peak at 380 nm belongs to π–π* transition, which corresponds to intense B-band (Soret band) of Cu-Phthalocyanine ring, which significantly instigates the electronic conduction mechanism. Further, to understand the electronic properties, a broad-band impedance analyzer was utilized, wherein dielectric permittivity at 10 MHz ∼ 0.049) were observed of β-CuPc/ABS. These low loss characteristics are a remarkable outcome of nanocomposites at MHz frequencies. Therefore, the authors believe that these nanocomposite films fabricated via the cost-effective solvent cast film technology could facilitate to develop organoelectronic components or devices.
