In this research work, polymer coated magnetic nanoparticles were prepared by co-precipitation method. The samples were characterized by XRD, SEM, EDS, VSM and two probe DC conductivity measurements. XRD pattern indicated the existence of a sole cubic phase of Fe3O4 with Miller indices (2 2 0), (3 1 1), (5 1 1), (4 4 0). An average size of magnetic nanoparticles was about 22.9 nm and it was reduced to 21.3 nm and 19.4 nm after 1 wt. %. and 2 wt. % coating of PEG-6000, respectively. The morphology and size of the samples were investigated by scanning electron microscope (SEM). EDX spectra confirmed the coating of PEG on magnetic nanoparticles. Magnetic properties were examined by vibrating sample magnetometer (VSM). Saturation magnetization (M s ) decreased as the concentration of PEG increased in the magnetic material. Electrical properties of uncoated and polymer coated Fe3O4 nanoparticles were studied by two-probe conductivity meter. This study concluded that the thermal flow of charge in polymer coated magnetic nanoparticles can be evaluated at micro and nano level.

“…MEMS were first developed in the microelectronics industry. The rapid growth of integrated circuit (IC) industry is connected with MEMS which were used to produce tiny devices [14], such as sensors [15], switches [16], filters [17], and silicon gears [18]. Nowadays, in various markets, such as automotive, electronics, medical, communications and defensive technologies, MEMS find many applications [19].…”

In this work, a novel polystyrene/Fe 3 O 4 nanocomposite prepared by in-situ method is presented. Magnetic Fe 3 O 4 nanoparticles were encapsulated by polystyrene. The FT-IR spectra confirmed polystyrene/Fe 3 O 4 nanocomposite preparation. The electrical properties of prepared nanocomposite were investigated by cyclic voltammetry (CV). The CV analysis showed good electrical conductivity of the synthesized nanocomposite. Magnetic properties of the nanocomposite were studied by vibrating sample magnetometer (VSM). The VSM analysis confirmed magnetic properties of the nanocomposite. The morphology and the size of the synthesized nanocomposite were investigated by field emission scanning electron microscope (FESEM). According to the VSM and CV results, such nanocomposite can be used in microelectromechanical systems.
