The invention discloses a preparation method and device for wrapping
metal wires with
carbon nanomaterials. The preparation method comprises the following steps: the
metal wires are neatly arranged and bundled together to form capillary tubes, then the capillary tubes are soaked in a suspension containing the
carbon nanomaterials, after being taken out, the capillary tubes are subjected to
evaporation drying, the soaking, the taking-out and the
evaporation drying of the capillary tubes can be repeated, and then the
metal wires bundled together are separated to obtain the metal wires wrapped with the
carbon nanomaterials; the metal wires arranged neatly and bundled together and wrapped with the carbon
nanomaterials are soaked in a
graphene suspension again, and then the metal wires bundled together are separated to obtain metal wires sequentially wrapped with carbon nano tubes and
grapheme; the metal wires are neatly arranged and bundled together and soaked into a carbon
nano tube and
grapheme mixed suspension, and are subjected to
evaporation drying, the soaking, the taking-out and the evaporation drying of the metal wires can be repeated for multiple times, and then the metal wires bundled together are separated to obtain metal wires wrapped with the carbon nano tubes and
grapheme. The method is simple, is easy to realize industrial production and has very wide application prospects in the fields, such as
electromagnetic shielding, conducting cables, flexible electronic devices, intelligent textiles, solar devices,
energy storage batteries, and linear supercapacitors.
