摘要: In this paper, electromagnetic wave absorbing characteristics of electrically conductive composites consisted polyaniline (PANi) and nanoparticles barium strontium titanate (BST) is described. The BST were synthesized by the mechanical alloying method successive particle size reduction steps through high frequency ultrasonic irradiation treatments. Whereas was produced oxidative polymerization processes which allows efficient control dielectric properties. Mechanical combined with treatments has resulted in powders a mean few nanometers (less than 100 nm). Such ultra-fine particles then used to synthesize BST/PANi nanocomposites 20:80, 50:50 80:20 compositions. physical properties like sizes, constant, absorption are investigated X-Ray Diffractometer, Fourier Transform Infrared, Vector Network Analyzer. It found that BST/polyaniline nanocomposite can enhance main absorber. constant conductivity support as absorber materials.In foun...
