摘要
目标。确定在表面活性剂胶束水溶液中获得的磁性材料(水性量子材料)的预期突发(意外)特性及其在精细技术中的应用。在不同性质的表面活性剂胶束水溶液中化学合成磁性纳米粒子。通过磁性测量、光谱法、衍射法、小角 X 射线衍射法、扫描探针显微镜等对磁性溶液和纳米粒子进行表征。所谓 "水量子材料",是指其特性主要由宏观尺度上的核量子效应(突现特性)决定的材料(胶束溶液)。胶束溶液表现出的现象和功能并不总是与经典的胶束化理论一致。文章详细介绍了实验结果,这些结果表明在表面活性剂的胶束水溶液中获得的磁性材料具有显现特性。特别是,十二烷基硫酸钠胶束水溶液中的 Gd3+ 离子表现出顺磁性,这可能表明它们在溶液中的随机排列与胶束上有序吸附层的经典胶束化理论相反。以氯化十六烷基吡啶为基质的量子材料中形成了铂钯混合纳米粒子,但 Gd3+ 离子必须被胶束上的 CP+ 离子排斥。在十二烷基硫酸钠胶束溶液中获得的钴铁氧体和镍铁氧体纳米粉末具有超顺磁性,尽管它们的前体离子存在于经典胶束的吸附层中应该会导致铁磁性。在量子材料中合成纳米粒子为在冶金废料处理过程中在一个阶段还原不同符号的离子提供了可能性,从而获得各种金属的纳米粒子及其复合材料。在量子表面活性剂材料中获得的磁性纳米粒子可在各种基底上自组装,从而制造出可在室温下控制其剩余磁化和矫顽力场的材料。
Emergent properties of magnetic ions and nanoparticles in micellar solutions of surfactants: Use in fine technologies
Objectives. To establish expected emergent (unexpected) properties of magnetic materials when obtained in aqueous micellar solutions of surfactants (aqueous quantum materials), and their use in fine technologies.Methods. Chemical synthesis of magnetic nanoparticles in aqueous micellar solutions of surfactants of various nature. Characterization of magnetic solutions and nanoparticles by magnetic measurements, spectroscopy, diffractometry, small-angle X-ray diffraction, scanning probe microscopy, and others.Results. The term “water quantum material” refers to materials (micellar solutions) whose properties are mainly determined by the nuclear quantum effect on macroscopic scales (emergent property). Micellar solutions exhibit phenomena and functionality not always consistent with the classical theory of micellization. The article presents in detail the experimental results that suggest the manifestation of the emergent properties of magnetic materials obtained in aqueous micellar solutions of surfactants. In particular, Gd3+ ions in an aqueous micellar solution of sodium dodecyl sulfate exhibit paramagnetic properties, possibly indicating their random arrangement in solution contrary to the classical theory of micellization with an ordered adsorption layer on micelles. Hybrid Pt–Gd nanoparticles are formed in a quantum material with cetylpyridinium chloride as a matrix, although Gd3+ ions must be repelled by CP+ ions on micelles. Nanosized powders of cobalt ferrite and nickel ferrite obtained in a micellar solution of sodium dodecyl sulfate have superparamagnetic properties, although the presence of their precursor ions in the adsorption layer in classical micelles should lead to ferromagnetic properties.Conclusions. The synthesis of nanoparticles in a quantum material opens up the possibility of reducing ions of different signs in one stage during the processing of metallurgy waste, in order to obtain nanoparticles of various metals and their composites. Magnetic nanoparticles obtained in a quantum surfactant material self-assemble on various substrates, enabling the creation of materials whose residual magnetization and coercive field can be controlled at room temperatures.
