Polymer blends of poly vinyle chloride (PVC) and polyaniline (PANI) with the inclusion graphene nano platelets (GNP) are fabricated to enhance EMI shielding effectiveness. The initial assessment cyclic voltammetry has shown improved electrical conductivity both for PVC/PANI PVC/PANI/GNP composites. capacitive effect composites is evaluated at lower frequency region (100 Hz−5 MHz). measurements performed in range 10 MHz–20 GHz. In case (15 wt%) blends, a maximum attenuation ∼27 dB attained...
Abstract The nanocomposites of PVDF/FLG and PVDF/GO are prepared using the solution casting method for varying concentrations FLG GO from 0.1 to 1 wt% in PVDF matrix. effect dispersion observed with help Scanning electron microscopy (SEM) x-ray diffraction confirming good samples also characterized thermal mechanical properties Differential scanning calorimetry (DSC) universal testing machine (UTM). nanofillers seemed increase tensile strength 10 MPa 20 variation crystallinity get maximum...
This study is based upon the functionalization of polypropylene (PP) by radical polymerization to optimize its properties influencing molecular weight. Grafting PP was done at different concentrations maleic anhydride (MAH) and benzoyl peroxide (BPO). The effect on viscosity during after reaction studied torque rheometer melt flow index. Results showed that a higher concentration BPO led excessive side-chain reactions. At high percentage grafting, lower weight product produced, which...
This study reports on the electrical conductivity, dielectric, and electromagnetic interferenc (EMI) shielding properties of conductive epoxy/PAni blend containing various concentrations. Polyaniline (PAni) was synthesized using oxidative chemical polymerization technique then dispersed into epoxy resin a sonication bath. Infrared spectra confirm curing composites. Increasing aspect ratio PAni in increased conductivity improves microwave absorption composites range (0.1 GHz–20 GHz)....
Ultrasound imaging is a widely used technique in every health care center and hospital. gel as coupling medium all ultrasound procedures to replace air between the transducer patient's skin, waves have trouble traveling through air. This research was performed formulate an inexpensive alternative commercially available it expensive imported from other countries. Different formulations with different concentrations of carbopol 980 (CAR 980) methylparaben were prepared natural ingredients such...
Polypyrrole (PPy) and barium hexaferrite (BaFe) were prepared successfully by chemical polymerization co-precipitation method, respectively. Nanocomposites based on polyvinyl chloride (PVC) matrix with different compositions of PPy BaFe fabricated solution casting method 0.5 mm film thickness. The key application these nanocomposites is the electromagnetic interference (EMI) shielding in microwave frequency (0.1 GHz-20 GHz) infrared (IR) near-infrared (NIR) wavelength (700–2500 nm). effect...
Abstract The Electromagnetic Interference (EMI) shielding characteristics of PVC based nanocomposites were studied when reinforced with newly developed Thermally Reduced Graphene Oxide (TRGO) coated Polyaniline (PANI) nanoparticles. Various techniques utilized to characterize prepared nanocomposite films like Scanning Electron Microscopy (SEM), direct current (DC) conductivity measurement, impedance analyses, and EMI shielding. was measured in three different regions the electromagnetic...
Polyester fibers (PEF) were successfully coated with Polyaniline (PANI) via in situ polymerization to make electrically conductive (ECF). X-ray diffraction (XRD) analysis confirms the synthesis and scanning electron microscopy (SEM) coating of PANI on surface PEF. Both uncoated tested for their DC conductivity, results showed a clear difference between two. From highly insulating state, it transitions about 0.1 S/cm. tensile strength modulus seemed rise, going from 0.5 MPa 2.5 0.04 0.4 MPa,...
