Hybrid ternary nanomaterials based on conjugated polymer polydiphenylamine-2-carboxylic acid (PDPAC) (poly--phenylanthranilic acid), FeO nanoparticles and single-walled carbon nanotubes (SWCNT) were prepared for the first time. Polymer-metal-carbon FeO/SWCNT/PDPAC nanocomposites were synthesized via in situ oxidative polymerization of diphenylamine-2-carboxylic acid (DPAC) by two different ways: in an acidic medium and in the interfacial process in an alkaline medium. In an alkaline medium (pH 11.4), the entire process of FeO/SWCNT/PDPAC-1 synthesis was carried out in one reaction vessel without intermediate stages of product extraction and purification. In an acidic medium (pH 0.3), to prepare the FeO/SWCNT/PDPAC-2 nanocomposites, prefabricated magnetite nanoparticles were deposited on the surface of obtained SWCNT/PDPAC-2. The phase composition of the nanocomposites does not depend on the synthesis reaction medium pH. The influence of the reaction medium pH on the structure, morphology, thermal, magnetic, and electrical properties of the obtained ternary nanocomposites was studied.
首次制备了基于共轭聚合物聚二苯胺 - 2 - 羧酸（PDPAC）（聚 - 对苯氨基苯甲酸）、FeO纳米颗粒和单壁碳纳米管（SWCNT）的混合三元纳米材料。通过两种不同方式，即酸性介质中以及碱性介质中的界面过程，经由二苯胺 - 2 - 羧酸（DPAC）的原位氧化聚合反应合成了聚合物 - 金属 - 碳FeO/SWCNT/PDPAC纳米复合材料。在碱性介质（pH 11.4）中，FeO/SWCNT/PDPAC - 1的整个合成过程在一个反应容器中进行，无需产物提取和纯化的中间阶段。在酸性介质（pH 0.3）中，为制备FeO/SWCNT/PDPAC - 2纳米复合材料，将预制的磁铁矿纳米颗粒沉积在所得SWCNT/PDPAC - 2的表面。纳米复合材料的相组成不依赖于合成反应介质的pH值。研究了反应介质pH值对所得三元纳米复合材料的结构、形态、热学、磁学和电学性质的影响。
