High Performance Thermoplastic Blends Modified by Potassium Hexatitanate for Dielectric Applications

What is it about?

In the present research, we explored the dielectric properties of polyvinylidene fluoride/polymethyl methacrylate blends modified by inorganic potassium hexatitanate (K 2 Ti 6 O 13). The phase and structural morphology of the samples were analyzed in detail using X-ray diffraction, polarizing optical microscope, scanning electron microscope, and atomic force microscope (AFM) techniques. Microscopic analysis of the modified blends exhibits the effect of filler over the surface morphology of the polymer phases. The thermal properties of the prepared samples were estimated using thermogravimetric analysis. The dielectric properties of the modified blends were measured across broadband frequency as a function of temperature (30–150° C). Dielectric constant (ε r) was increased as a function of loading of K 2 Ti 6 O 13 and decreased to relative dissipation factor (tanδ). Nanoscale two dimensional and three dimensional AFM topographic phase images demonstrated the effect of K 2 …
