This study explained on the effect of plasticizer ethylene carbonate (EC) on the properties of 30% poly (methyl methacrylate) grafted natural rubber grafted (MG30) doped with ammonium triflate (NH4CF3SO3) are investigated. The influence of salt concentration and with different proportion of plasticizer on the conductivity has been presented. The ac impedance study showed the conductivity reaches up...
In this work, the phase transition from the paraelectric α phase to the ferroelectric β phase during uniaxial stretching of PVDF films at rates between 1 and 1000 mm/min was investigated. In our experiments, the final stretching ratio and the temperature during stretching were 4.5 and 110°C, respectively. The comparison of Infra Red (IR) spectra obtained on unstretched and stretched films shows that...
Cobalt-doped Zinc oxide thin film was deposited onto SiO2/Si substrate using polymer-assisted deposition method. The surface morphology, phase structure and chemical state of the thin film were characterized by SEM, XRD, and XPS. The gas-sensing characteristics of the thin film upon exposure to aromatic organic compound vapors were investigated with a home-made sensor measurement system. The current...
The CdSe nanoparticles have been synthesized by hot-injection method, and thermal annealing was used to improve the crystallinity of synthesized nanoparticles and reconstruct the surface of nanoparticles. The synthesized and annealed CdSe nanoparticles were characterized by TEM, XRD and PL spectra. After thermal annealing followed by a solvent exchange process, the CdSe nanoparticles were used to...
Summary form only given. Successful deposition of nano-phase crystalline TiO2 thin films on polymeric substrates, polymethylmethacrylate (PMMA) and knitted polyethylene (PE) at room temperature was achieved using the dense plasma focus (DPF) device. Deposition was achieved using argon- oxygen gas mixture in the ratio of 9:1 after evacuating the chamber to a base pressure of 10-5 mbar. The working...
