Barium titanate flakes based composites for microwave absorbing applications

One-dimensional carbon nanotube@barium titanate@polyaniline multiheterostructures for microwave absorbing application

Multiple-phase nanocomposites filled with carbon nanotubes (CNTs) have been developed for their significant potential in microwave attenuation. The introduction of other phases onto the CNTs to achieve CNT-based heterostructures has been proposed to obtain absorbing materials with enhanced microwave absorption properties and broadband frequency due to their different loss mechanisms. The existe...

Synthesis of nanosized barium titanate/epoxy resin composites and measurement of microwave absorption

Barium titanate/epoxy resin composites have been synthesized and tested for microwave absorption/ transmission. Nanocrystalline barium titanate (BaTiO3 or BT) was synthesized by the hydrothermal method and the composites of BT/epoxy resin were fabricated as thin solid slabs of four different weight ratios. BTwas obtained in the cubic phase with an average particle size of 21 nm, deduced from th...

Physical structure of P(VDF-TrFE)/barium titanate submicron composites

studies on nano barium strontium titanate/cellulose derivatives composites

studies were carried out on the preparation and properties of the composites made from cellulose acetate butyrate and cellulose acetate propionate with various amounts of barium strontium titanate nano-particle. the nano-particles of barium strontium titanate (bst) with formulation of ba0.77sr0.23tio3 were made by sol-gel method and their purity and particle size were analyzed by x-ray diffract...

Sputtered Modified Barium Titanate for Thin-Film Capacitor Applications

New apparatus and a new process for the sputter deposition of modified barium titanate thin-films were developed. Films were deposited at temperatures up to 900 °C from a Ba₀.96Ca0.04Ti0.82Zr0.18O₃ (BCZTO) target directly onto Si, Ni and Pt surfaces and characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) and X-ray photoelectron spectroscopy (XPS). Film texture and cryst...
