Embodiment Construction

[0015] The present invention will be further described below in conjunction with the accompanying drawings and technical solutions.

[0016] A kind of unpowered self-propelled micro-boat collecting water droplets such as figure 1 As shown, it consists of a superhydrophobic hull 1, a cage 2, a water collecting device 3, a superhydrophilic wedge pattern 4 and a superhydrophilic water jet oblique hole 5. The superhydrophobic hull 1 is made of 1060 aluminum sheet with a thickness of 0.6mm, the length of the hull is 40mm, the width is 15mm, and the contact angle to water is not less than 150°. The super-hydrophobic hull 1 is connected and fixed with two cages 2 by welding, the cage 2 is connected to the water collecting device 3 by bolts, the inclination angle of the water collecting device 3 is adjusted to 30°, and the water collecting device 3 is etched on the water collecting device 3 by laser A superhydrophilic wedge-shaped pattern 4 is processed, and the end of the superhydro...

Abstract

The invention relates to a water drop collecting type unpowered self-propelled micro boat, which comprises a super-hydrophobic hull, a cage, a water collecting device, a super-hydrophilic wedge pattern and a super-hydrophilic water jet slant hole. The super-hydrophobic hull and the cage are connected by bolts or welded, and the water collecting device and the cage can be connected by bolts to facilitate the adjustment of the angle of the water collecting device. A super-hydrophilic wedge-shaped pattern is processed on the upper surface of the water-collecting device, and the rest is a super-hydrophobic region. The superhydrophilic water jet slant hole is processed on the surface of the superhydrophobic hull. The axis direction of the slant hole is at a certain angle to the forward direction of the micro-boat, and the slant hole is located directly below the water outlet at the end of the superhydrophilic wedge pattern. The invention has the advantages of cleanness, no pollution, fast transportation speed, etc., and can realize self-driven transportation without power by collecting water droplets.

Description

technical field [0001] The invention belongs to the technical field of self-propelled transportation devices, and relates to a water drop collecting type unpowered self-propelled miniature ship. Background technique [0002] Unpowered self-propelled transport refers to the spontaneous directional transport without external power source or electric drive device, which has important application value in the fields of microfluidic control, mist collection, and delivery of trace drugs. According to different driving principles, the existing unpowered self-driving methods can be divided into two types: catalytic driving type and external energy field driving type. The catalytically driven type refers to a specific catalyst coated on the device, which directly converts chemical energy into mechanical energy through catalytic action, and then promotes the structure to realize self-driven motion. Literature Advanced Materials, 2015, 27, 4411 reported a catalyst Pt, MnO 2 The nanop...
