Electromagnetic Shielding Effectiveness of Wollastonite/PANI/Colemanite Composites

Abstract

In this study, composites of wollastonite-colemanite were produced by using mixed oxide technique. The wollastonite-colemanite compositions were formed with various proportions for the structural analysis. The results of wollastonite-colemanite structural analysis indicated that second phase did not form in wollastonite and colemanite. The single phases wollastanite-colemanite compounds were measured after sintering between 900-1100°C for X-ray diffraction (XRD). Addionality, the wollastonite/polyaniline/colemanite composites were produced by hot pressing using the compositions of wollastonite-colemanite in different proportions and aniline. The weight ratios of (wollastonite-colemanite) and aniline were 1:1 respectively and epoxy resin was used to produce microwave shielding effectiveness composites. The microwave shielding performances of wollastonite/polyaniline/colemanite composites were investigated by shielding effect in 0 –8 GHz, using two–port vector network analyzer (VNA). A minimum of – 41.65 dB shielding effectiveness performance was obtained in 6.26 GHz at the thickness of 1.5 mm. According to the parameters determined in terms of properties, the wollastonite-colemanite compounds were produced as composite with a PANI base and their features were characterized for shielding effect. This microwave shielding performance can be modulated simply by controlling the content of polyaniline and content of wollastonite-colemanite in the samples for the wider and required frequency bands.
