Abstract

This α-Vanadyl phosphate, VOPO₄.2.5H₂O(VOP), and TiO₂ were prepared and characterized. α-Vanadyl phosphate/titanium dioxide, [TiO₂]_0.25 [VOP]_0.75, nanocomposite was synthesized by dispersing an ethanol suspension. Polymers, polyaniline, polypyrrole, polyindole, and polycarbazole were prepared via self-support of their monomers polymerization, where (VOP/TiO₂) acts as an oxidant. The VOPO₄· 2.5 H₂O (V⁺⁵OP) acts as self-supporting monomers in polymerization, due to part of it being converted to (V⁺⁴OP), TiO₂ enhances the process. Their matrix was confirmed by scanning electron microscopy analysis, Fourier transforms infrared (FT-IR) and ultraviolet-visible (UV-Vis). Color changes support the formation of the polymers. The % in wt. of the polymers was obtained from elemental (CHN)analysis. Their electrical conductivity shows a semiconductor trend.

氧化钛-磷酸钒纳米复合材料自支撑苯胺、吲哚、吡咯和咔唑聚合剂

制备了α-磷酸钒基、voo4.2.5 h2o （VOP）和TiO2，并对其进行了表征。采用乙醇悬浮液分散法制备α-磷酸钒基/二氧化钛（[TiO2]0.25 [VOP]0.75）纳米复合材料。以（VOP/TiO2）为氧化剂，通过单体自支撑聚合法制备了聚苯胺、聚吡咯、聚吲哚和聚咔唑等聚合物。voo4·2.5 H2O （V+5OP）作为自支撑单体在聚合过程中，由于其部分转化为（V+4OP）， TiO2增强了聚合过程。通过扫描电镜分析、傅里叶变换红外（FT-IR）和紫外-可见（UV-Vis）证实了它们的基质。颜色变化支持聚合物的形成。通过元素（CHN）分析得到聚合物的wt %。它们的电导率呈半导体趋势。

期刊介绍： Nano-Structures & Nano-Objects is a new journal devoted to all aspects of the synthesis and the properties of this new flourishing domain. The journal is devoted to novel architectures at the nano-level with an emphasis on new synthesis and characterization methods. The journal is focused on the objects rather than on their applications. However, the research for new applications of original nano-structures & nano-objects in various fields such as nano-electronics, energy conversion, catalysis, drug delivery and nano-medicine is also welcome. The scope of Nano-Structures & Nano-Objects involves: -Metal and alloy nanoparticles with complex nanostructures such as shape control, core-shell and dumbells -Oxide nanoparticles and nanostructures, with complex oxide/metal, oxide/surface and oxide /organic interfaces -Inorganic semi-conducting nanoparticles (quantum dots) with an emphasis on new phases, structures, shapes and complexity -Nanostructures involving molecular inorganic species such as nanoparticles of coordination compounds, molecular magnets, spin transition nanoparticles etc. or organic nano-objects, in particular for molecular electronics -Nanostructured materials such as nano-MOFs and nano-zeolites -Hetero-junctions between molecules and nano-objects, between different nano-objects & nanostructures or between nano-objects & nanostructures and surfaces -Methods of characterization specific of the nano size or adapted for the nano size such as X-ray and neutron scattering, light scattering, NMR, Raman, Plasmonics, near field microscopies, various TEM and SEM techniques, magnetic studies, etc .
