چکیده

The mechanical mixtures of titanium oxide (TiO2) with carbon nanostructures for 3D printing CJP technology, which are used as consumables the manufacturing electrically conductive composite products, created in this work. Various (single- and multi-walled nanotubes nanofibers) were creation products (TiO2–СNS) by technology. Optimal conditions processing (TiO2/MWCNT) on a planetary ball mixer (CJP) studied proposed. dose deformation influence mixture under optimal mechanochemical (76 J/g), allows not to deteriorate electrical conductivity material, is determined. dependence (CNS/TiO2, where CNS content 3 wt. %) type (SWCNT, MWCNT CNF) contained ceramics (TiO2), constructed. exponential specific (G) (TiO2–MWCNT) mass nanotubes, also recorded In framework study (CJP), fuel cell cathode based Pt/TiO2–MWCNT was created. It found that catalyst Pt/TiO2–MWCNT, contains 5 % has best catalytic activity oxygen recovery. At same time, average particle size platinum (Pt) 5–10 nm, while Pt EDX samples approximately ~10 %. Also, studies carried out from mixing Pt/TiO2-MWCNT composites 15 50 Samples analyzed transmission scanning electron microscopy.

Electrically Conductive Latex-Based Composites

Electrically conductive polymer composites filled with carbon black can exhibit the mechanical behavior of a polymer and metallic electrical conductivity. Unfortunately, excessive amounts of carbon black can produce brittle films and too little carbon black can result in low conductivity. Composite conductivity can be dramatically improved by using latex as the matrix starting material. Latex p...

Electrically small antennas (ESAs) are becoming one of the key components in the compact wireless devices for telecommunications, defence, and aerospace systems, especially for the spherical one whose geometric layout is more closely approaching Chu's limit, thus yielding significant bandwidth improvements relative to the linear and planar counterparts. Yet broad applications of the volumetric ...

Electrically Conductive Low Dimensional Nanostructures: Synthesis, Characterisation and Application

Multi-walled carbon nanotubes modified by covalent grafting of poly(2-vinylpyridine) (CNT-g-P2VP) form stable dispersions in good solvents for P2VP, including water at low pH. The positively charged P2VP shell allows the immobilization of the CNTs onto oppositely charged surface. Deposition of CNT-g-P2VP from aqueous dispersions at low pH is an effective method to prepare homogeneous ultra-thin...
