Preparation and Characterization of Poly(vinyl alcohol)/ferrofluid Composite for Use as Anti Electrostatic Discharge Material
Type Of :
In this project, ferrofluid was synthesized by a co-precipitation method between iron (III) chloride hexahydrate and iron (II) chloride tetrahydrate with a 2:1 ratio in ammonium hydroxide solution, using tetramethyl ammonium hydroxide as a surfactant. The synthesized ferrofluid exhibited the viscosity of 6.5 cP. The chemical structure of Fe3O4 particle was investigated using X-ray diffraction (XRD) and Fourier-transform infrared spectroscopy (FT-IR). Scanning electron microscopy (SEM) analysis was carried out to study the surface, dispersion as well as particle size of Fe3O4. The synthesized ferrofluid was later used as a conductive filler in the preparation of polyvinyl alcohol/ferrofluid composites, at various ratios e.g., 0 ,5 ,10 ,15 and 20% w/w. Glutaraldehyde (0.5% w/w by weight of the polyvinyl alcohol) was used as a crosslinker. In order to evaluate the potential for use as anti-electrostatic discharge material, the properties of the prepared composites, such as mechanical properties, surface morphology, surface resistivity, and swelling ratio in water, were also investigated. The experimental results showed that the prepared composites exhibited the variation in mechanical properties, morphology, surface resistivity, and swelling ratio in water, depending on the Fe3O4 content. In conclusion, 10%w/w ferrofluid was the suitable amount for preparing the composite for use as anti-electrostatic discharge material.
