Description

technical field

[0001] The invention belongs to the technical field of nanometer materials and thin film materials, and in particular relates to a transplantable ultrathin nanoporous gold membrane and a preparation method thereof. technical background

[0002] Nanomaterials are obviously different from traditional continuous solid materials. Due to the effect of nanometer size and large specific surface area, such materials will exhibit special physical and chemical properties, including special photoelectric functional properties, transport properties and mechanical properties. Nanomaterials come in many forms, such as nanoparticles, nanorods, nanowires, nanometer-thick films, and nanosolid (nanophase) materials. The definition of nanomaterials is mainly based on scale effects, so nanomaterials can be nanoscale entities or nanoscale spaces.

[0003] Porous noble metal materials have attracted extensive attention due to their excellent chemical stability and wide applicatio...
