High dielectric polymer composites are used in electronic devices and electrical systems. Our modified strontium titanate powder has excellent properties with its high dielectric constant, low loss, surface area, particle size, particle size distribution and dispersion properties to use in polymer composites. In case of polymer -matrix composites some low cost shaping techniques like screen printing, tape casting, injection molding can be used in device fabrication.

Nanosized inorganic fillers (BaTiO3, SrTiO3 etc.) give enhanced thermomechanical, dielectric and optical properties to polymer composites. Studies show that biocompatible chitosan and cellulose based biopolymers can be used with SrTiO3 nanoparticles to form bio-composites for electronic applications (Declet-Vega, A., Ramos, N., Montoya, S., Suarez, O., “Bio-composites reinforced with SrTiO3 nanoparticles: mechanical behaviour and degradability”,Journal of Composites Science, 2019)

It can be used in microwave capacitors, flat panel displays, thermistors and varistors, semiconductive ceramics, pyroelectric detectors. These titanate based polymer composites are used to overcome “Electromagnetic interference-EMI” problem which is the side effect of various devices such as cellular phones, television, radars, telephone microwave delay systems. Sambyal et al. Reported that barium-strontium titanate- polymer composites have good properties for EMI shielding applications (Sambyal, P., Singh, A., Verma, M., Farukh, M., Singh, B., Dhawan, S.,”Tailored polyaniline/barium strontium titanate/expanded graphite multiphase composite for efficient radar absorbtion”, RSC Advances, 24, 2014)
