Abstract

Mostly-uniform spherical mushrooms like MWCNT/SiO₂@ZnO nanocomposite was synthesized under microwave power and characterized using TEM, XRD, EDX, TG/DTA and FT-IR techniques. The modified chemical process was used in three steps for the synthesis of the nanocomposite. Having a nano-capillary structure of MWCNT as nano-core, chemically and physically inert silica cover are a vital backbone for ZnO, which is a semiconductor. Because of the excellent chemical and physical properties of MWCNT/SiO2@ZnO nanocomposite, it has shown unique catalytic properties in the photocatalytic degradation of methyl blue. Approximately all of the methyl blue was degraded in water in 10 min. under sun-light and after 60 min., rarely left from dye in the water. The thermal and electrical behavior of mushrooms like nanocomposite doped E7 was investigated. According to the obtained results, the nematic to isotropic phase transition temperature of sample enhanced with nanocomposite dispersion and threshold voltage of mushroom like nanocomposite doped Nematic Liquid Crystal E7 decreased was founded.

微波辅助合成MWCNT / SiO 2 @ZnO纳米复合材料蘑菇：对向列液晶E7的影响和高效光催化活性对甲基蓝的降解

摘要

大部分均匀的球形蘑菇，例如MWCNT / SiO ₂在微波功率下合成了ZnO纳米复合材料，并利用TEM，XRD，EDX，TG / DTA和FT-IR技术对其进行了表征。改进的化学过程在三个步骤中用于合成纳米复合材料。具有作为纳米核的MWCNT纳米毛细管结构，化学和物理惰性二氧化硅覆盖物是半导体ZnO的重要骨架。由于MWCNT / SiO2 @ ZnO纳米复合材料具有出色的化学和物理性能，因此在光催化降解甲基蓝中表现出独特的催化性能。在10分钟内，大约所有的甲基蓝在水中都被降解。在阳光下60分钟后，几乎没有染料残留在水中。研究了类似纳米复合掺杂E7的蘑菇的热和电行为。根据获得的结果，
