Abstract
The Hexagonal Boron Nitride (hBN) nanoplatelets are synthesized using a wet chemical method. X-Ray Diffraction (XRD) shows the hBN nanoplatelets exfoliates along the (002) plane. Transmission Electron Microscope (TEM) observation shows the exfoliated hBN nanoplatelets. The hBN nanoplatelets and polyphenylene suulfiude (PPS) physical mixture are solvent processed using ethyl alcohol. It involves two step processing with the first step of ultrasonic treatment of hBN nanoplatelet in ethyl alcohol followed by mixing it with PPS powder and further sonication. This mixed powder of PPS and hBN nanoplatelets are hot pressed using a compression moulding machine. With more addition of hBN nanoplatelets in PPS matrix shows the enhancement in dielectric constant. In addition, the dispersion of hBN nanoplatelets in the PPS matrix increases the crystallinity and thermal stability.
