Abstract

ABSTRACT: Hexagonal boron nitride nanoparticles (h-BNNPs)/Chitosan (CS)/Hydroxypropyl methylcellulose (HPMC) based ternary nanocomposites were prepared using solution casting method and characterized using Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), thermogravimetric analyses (TGA), Scanning electron microscopy (SEM) and Atomic force microscopy (AFM). The dielectric properties of CS/HPMC/h-BNNP nanocomposite films were also investigated as a function of frequency and temperature and a maximum dielectric constant of ~1200 was achieved at 5 wt % of h-BNNP loading in CS/HPMC blend matrix. The results from the structural, morphological and thermal studies revealed good interactions between h-BNNPs, CS and HPMC. Graphical Abstract:
