Ni Ion-Induced Optical, Structural, and Electrical Properties of Polyaniline/Polyvinyl Chloride Composites
Thin films of polyaniline/polyvinyl chloride (PANI/PVC) composites synthesized and irradiated with a nickel ion (Ni7+) beam using flux of 3.125\(\times\)109 particles/cm2/s and fluence ranging between 3\(\times\)1011 and 1\(\times\)1013 particles/cm2 were investigated with respect to their optical, structural, and electrical properties. The photoluminescence (PL) analysis showed that swift heavy ion (SHI) irradiation caused the creation of new color centers, which were diminished at greater fluence. With irradiation, both the direct and indirect band gaps decreased, making the materials more conducive to conduction. However, the direct band gap was smaller than the indirect band gap. Fourier transform infrared (FTIR) analysis showed that the aromatic nature of PANI was not disturbed by SHI irradiation. The variation in capacitance with frequency indicated that the material can be used for electromagnetic interference (EMI) shielding, and the shielding properties are modified by ion irradiation. Scanning electron microscopy (SEM) analysis revealed that irradiation of the polymer with Ni7+ leads to chain scissoring and cluster formation, whereas at higher fluence, smaller parts are rearranged to form micro-clusters.
期刊介绍：
The Journal of Electronic Materials (JEM) reports monthly on the science and technology of electronic materials, while examining new applications for semiconductors, magnetic alloys, dielectrics, nanoscale materials, and photonic materials. The journal welcomes articles on methods for preparing and evaluating the chemical, physical, electronic, and optical properties of these materials. Specific areas of interest are materials for state-of-the-art transistors, nanotechnology, electronic packaging, detectors, emitters, metallization, superconductivity, and energy applications.
Review papers on current topics enable individuals in the field of electronics to keep abreast of activities in areas peripheral to their own. JEM also selects papers from conferences such as the Electronic Materials Conference, the U.S. Workshop on the Physics and Chemistry of II-VI Materials, and the International Conference on Thermoelectrics. It benefits both specialists and non-specialists in the electronic materials field.
A journal of The Minerals, Metals & Materials Society.
