specific Embodiment approach 1
[0019] Specific Embodiment 1: In this embodiment, the carbon fiber / zinc oxide-zinc selenide double-shell microwire nano-generator nanomaterial grows zinc oxide nanowires with a length of 0.9-1.1 μm along the direction perpendicular to the carbon fiber axis. A zinc selenide layer is grown on the tips of the nanowires.
[0020] The carbon fiber / zinc oxide-zinc selenide double-shell microwire nanogenerator nanomaterial described in this embodiment is a quasi-one-dimensional nanowire with a double-shell structure along the vertical axis; Zinc-zinc selenide double-shell structure, the nanomaterial will output a large amount of current when a small pressure is applied perpendicular to the direction of the nanogenerator nanomaterial; repeated experiments have shown that the performance of the nanomaterial is stable and can be used for continuous work.
specific Embodiment approach 2
[0021] Embodiment 2: This embodiment differs from Embodiment 1 in that the diameter of the zinc oxide nanowires is 50-70 nm.
[0022] In this embodiment, zinc oxide nanowires are grown along the radial direction of the carbon fiber, wherein the cross section of the zinc oxide nanowires is hexagonal.
specific Embodiment approach 3
[0023] Embodiment 3: This embodiment is different from Embodiment 1 or Embodiment 2 in that the thickness of the zinc selenide layer is 100-110 nm.
