Abstract
Optical properties and surface morphology of pure and doped Polystyrene films with different divalent metals of Zn, Cu and Sn and one concentration percentage have been studied. Measurements of UV-Vis spectrophotometer and AFM spectroscopy were determined. The absorbance, transmittance and reflectance spectrums were used to study different optical parameters such as absorption coefficient, refractive index, extinction coefficient and energy gap in the wavelengths rang 200-800nm. These parameters have increased in the presence of the metals. The change in the calculated values of energy gaps with doping metals content has been investigated in terms of PS matrix structural modification. The value of optical energy gap was found decreasing from 4.5eV of pure PS to reach 4.45, 4.38 and 4.32eV for Zn, Cu and Sn respectively. Measurement by AFM spectroscopy was done for two and three dimensional topographic images. From figures, the data of roughness average were 7.29, 7.31, 3.37 and 6.73nm for samples (Blank, Zn, Cu and Sn) respectively.
Highlights
The electronic components majority in microelectronic circuits is passive and raise above 80% of the surface area for printed wired
The overall performance of the heterogeneous system was affect by the dispersion of an electrically conductive phase within an insulating polymer matrix
It was reported that if the scattered metallic particle is in suitable quantity, semiconductive or a conductive composite is generated
Summary
The electronic components majority in microelectronic circuits is passive and raise above 80% of the surface area for printed wired. The overall performance of the heterogeneous system was affect by the dispersion of an electrically conductive phase within an insulating polymer matrix. It was reported that if the scattered metallic particle is in suitable quantity, semiconductive or a conductive composite is generated. Good properties of these systems make them technologically important and competitive to other alternate materials which lead to their cost-effectiveness. Conductive polymer composites are major for applications referring to electromagnetic interference (EMI) shielding, radio frequency interference (RFI) shielding, and electrostatic dissipation of charges (ESD). Composites can be realized as materials that contain two or more physically and chemically various phases separated via a distinct interface (1,2)
