Synergetic improvement in electromagnetic interference shielding characteristics of polyaniline-coated graphite oxide/γ-Fe2O3/BaTiO3 nanocomposites

Assessing magnetic nanoparticle aggregation in polymer melts by dynamic magnetic susceptibility measurements

“…Magnetic nanoparticles (MNPs) have been used as fillers in polymer nanocomposites in order to imbue the polymers with properties such as for electromagnetic interference shielding [33][34][35][36], for triggered drug release [37,38], and to enable magnetothermal repair of the damaged composite [39][40][41], among other applications [42][43][44][45]. For many of these applications it is ideal that the MNPs be well dispersed as single entities throughout the polymer matrix, such that their properties are predictable and such that their enhancement is uniform throughout the material.…”

Chemical Polymerization Kinetics of Poly-O-Phenylenediamine and Characterization of the Obtained Polymer in Aqueous Hydrochloric Acid Solution Using K2Cr2O7as Oxidizing Agent

“…Polyaniline as an electrically conductive polymer has attracted considerable attention, because of its excellent environmental stability in the electroconducting form and electrical and optical properties [1,2]. It has various potential applications in many high performance devices [3][4][5][6][7][8][9]. A common feature of conducting polymer is conjugation of -electrons extending over the length of the polymer backbone [10].…”

The Preparation and Research on the Electromagnetic Shielding Effectiveness of T-ZnO@Ag/Silicone Rubber Composites

“…After processing, it is a kind of functional rubber material and has extensive application in many industries, including aviation and space, ships, computers and power electronics, in which the Si rubber and the conductive fillers are used as the matrix and the shielding agent, respectively [1]. High-conductivity or high-magnetic-conductivity metal powders such as silver (Ag) powder, copper (Cu) powder and nickel (Ni) powder or metallic composite powders such as Ag-coated Ni powders, Ag-coated Cu powders and Agcoated aluminum (Al) powders have been used as conductive fillers in conventional electromagnetic shielding Si rubber [2,3]. However, these powder materials have several disadvantages, such as excessive cost, high density, and great filler consumption.…”
