Special Issue Information

Dear Colleagues,

Polymers are a class of materials which have different properties and consequently a variety of applications, depending on their properties. They are being used for diverse applications starting from insulating to conducting. Some of the polymers and their composites are used as electrolytes or insulating materials in electrical devices. There are conducting polymers, which are being used for energy storage applications such as transistors, sensors, photovoltaic, etc. Their electro-chemical and physical properties can be easily altered and controlled by external stimulations such as electricity, pH, light etc.  Polymer-based materials are widely used in bio-chemical applications. Since polymer materials are compatible with 3D printing, they are being used extensively in device fabrications.

This Special Issue focuses on the experimental and theoretical study of electrochemical aspect of polymers and polymer composites. This include synthesis of new polymer-based materials for any of the electrochemical applications or investigation of electrochemical properties of existing materials. Also, we encourage the submission of papers based on new methods/techniques on the fabrication of electrochemical cells. Similarly, we will accept papers on electro/thermo-chromic properties of polymers.

In this work, the effect of ion bombardment on the optical properties of Polymethylmethacrylate (PMMA) was studied. Polymer samples were implanted with 500 keV Cu+ ions with a fluence ranging from 1 × 1012 to 1 × 1014 ions/cm2 [...] Read more.
In this work, the effect of ion bombardment on the optical properties of Polymethylmethacrylate (PMMA) was studied. Polymer samples were implanted with 500 keV Cu+ ions with a fluence ranging from 1 × 1012 to 1 × 1014 ions/cm2. X-ray Diffractometer (XRD) study indicated a relatively lower variation with a higher dose of ions. Fourier Transform Infrared (FTIR) spectra exhibited that with the implantation of Cu ions the intensity of existing bands decreases, while the result confirms the existence of a C=C group. The pristine and ion-implanted samples were also investigated using photoluminescence (PL) and Ultra Violet-Visible (UV-VIS) spectra. The optical band gap (Eg) was observed up to 3.05 eV for the implanted samples, while the pristine sample exhibited a wide energy-gap up to ~3.9 eV. The change in the optical gap indicated the presence of a gradual phase transition for the polymer blends. The dielectric measurements of the pristine and Cu-implanted PMMA were investigated in the 10 Hz to 2 GHz frequency range. It was found that the implanted samples showed a significant decrease in the value of the dielectric constant. The value of the dielectric constant and dielectric loss of the PMMA and Cu-implanted samples at a 1-kHz frequency were found to be ~300 and 29, respectively. The modification of the PMMA energy bandgap in the current research suggested the potential use of Cu implanted PMMA in the field of optical communications and flexible electronic devices.
