Microemulsions have been revealed as feasible templates to grow magnetic nanostructures using an electrodeposition method. Reducing agents are not required and the applied potential has been used as driving force of the nanostructure growth. A systematic study of conductive microemulsion systems to allow the CoNi electrodeposition process has been performed. Different surfactants and organic components have been tested to form microemulsions with a CoNi electrolytic bath as an aqueous component in order to define the microemulsions showing enough conductivity to perform an electrodeposition process from the aqueous component. By using microemulsions of the aqueous electrolyte solution-Triton X-100-diisopropyl adipate system, CoNi electrodeposition has been achieved, the structure of the deposits being dependent on the composition and structure of the microemulsion, which can act as a soft-template to obtain different discontinuous deposits. The magnetic properties of the CoNi deposits vary with their structure.
微乳液已被证明是一种可行的模板，可以使用电沉积方法生长磁性纳米结构。不需要还原剂，并且施加的电势已被用作纳米结构生长的驱动力。已经对导电微乳液体系进行了系统研究，以允许 CoNi 电沉积过程。为了确定具有足够导电性以从水相成分进行电沉积过程的微乳液，已经测试了不同的表面活性剂和有机成分以形成具有 CoNi 电解质浴的微乳液作为水相成分。通过使用 Triton X-100-二异辛基己二酸酯体系的水电解质溶液的微乳液，已经实现了 CoNi 的电沉积，沉积物的结构取决于微乳液的组成和结构，微乳液可以作为软模板以获得不同的不连续沉积物。CoNi 沉积物的磁性能随其结构而变化。
