Description

technical field

[0001] The invention relates to the technical field of nano-synthesis, in particular to a method for growing high-entropy alloy nanoparticles on a flexible substrate. Background technique

[0002] Flexible electronics is an emerging electronic technology that fabricates organic / inorganic functional materials, electronic devices or systems on flexible substrates. It has a wide range of application prospects in the fields of information, energy, medical care, and national defense. High-entropy alloy nanoparticles are a new type of nanomaterials composed of five or more metal elements and have a single phase. In recent years, they have attracted extensive attention in the fields of catalysis, energy, and sensing.

[0003] Although traditional wet chemical methods are often used to synthesize alloy nanoparticles with different morphologies, sizes and structures, it is difficult to prepare multi-element alloy nanomaterials with more than three element combination...
