The article was titled 《Achieving C/CuO microfiber composites with efficient microwave absorbing performance at low thickness》.Electric Literature of C4H12KNaO10 The article contains the following contents:
The carbon fibers with low d. still face significant microwave absorbing application issues due to their high dielec. constant Herein, C/Cu core-shell microfiber composites are prepared by electroless plating. The Cu coating of C/Cu core-shell microfiber composites is oxidized to CuO at 300°C and 400°C temperature The morphol., microstructure, and electromagnetic characteristics of C/CuO microfiber composites were analyzed. The diameter of all the fiber composites was about 7-8μm. The CuO coating thickness formed at 300°C and 400°C temperature is 30-90 nm and 300-900 nm, resp. The annealing process tunes the electromagnetic characteristics and optimizes impedance matching. The min. reflection loss (RL) value of C/CuO core-shell microfiber composites annealed at 300°C temperature remarkably reaches – 46.0 dB at 1.06 mm thickness and 3.6 GHz effective absorption bandwidth (RL ≤ – 10 dB). The C/CuO microfiber composites can be the ideal absorbing materials at a lower thickness. The results came from multiple reactions, including the reaction of Potassium sodium (2R,3R)-2,3-dihydroxysuccinate tetrahydrate(cas: 6381-59-5Electric Literature of C4H12KNaO10)
Potassium sodium (2R,3R)-2,3-dihydroxysuccinate tetrahydrate(cas: 6381-59-5) is a ferroelectric crystal with a high piezoelectric effect and electromechanical coupling coefficient. Electric Literature of C4H12KNaO10 It is utilized to break up emulsion in organic synthesis as well as a common precipitant in protein crystallography.
