Description 876-882
Dielectric properties of nanosized Lithium Orthosilicate (Li4SiO4) and linear low-density polyethylene composite at
X-Band frequencies are investigated, to realize its utility as a substrate for microwave devices. Solid state technique is used
to synthesize nano Li4SiO4. To confirm the structural and morphological properties of the synthesized nano Li4SiO4, X-ray
diffraction, Fourier transformed infrared spectroscopy and transmission electron microscopy are used. Composites of nano
Li4SiO4 and linear low-density polyethylene matrix are synthesized with varying weight fraction of nano Li4SiO4 viz. 2%,
4% and 6%. The lateral portion of a fractured sample (composite) is examined using scanning electron microscope to
confirm homogeneous dispersion of nano Li4SiO4 in linear low-density polyethylene matrix. Water absorption measurement
of all the composites are carried out based on ASTM D570-98. Densities of the composites are measured via hydrostatic
weighing by using Archimedes principle. Complex permittivity and permeability measurement of the composites are
recorded by utilizing Nicholson-Ross approach. For all weight fraction of the nano inclusions, the real component of
permittivity and dielectric loss tangent of the composites in the X-band are found to be in the range of 2.2 – 2.6 and 10-2 –10-4,
respectively. Return losses for the composites are calculated from complex permittivity and permeability values to validate
its applicability as substrate for various high frequency applications.
