Problems solved by technology

However, the liquid transportation speed of this structure is slow, the track size parameters can only be changed in a small range, the application range is narrow, and the liquid is easy to stagnate at the two wedge-shaped joints, so continuous transportation cannot be realized, and the stability of continuous transportation is poor.

Embodiment 1

[0013] Such as figure 1 As shown, a structure that can realize long-distance self-propelled transport of liquid: it is mainly composed of a superhydrophobic substrate 1 and a series shuttle track 2 with arc transition; the series shuttle track structure consists of multiple shuttles with transition arcs The shuttle-shaped track structure is connected sequentially, and the junction is a transition area 3; there are many transition areas along the length direction of the series shuttle-shaped track; in this embodiment, the arc radius R 1 3mm, arc radius R 2 is 2mm, the initial width a is 0.4mm; the end width b is 2mm, and the total track length is 62.3mm. Such as figure 1 As shown, the aluminum sheet with the shuttle-shaped track structure in series is placed horizontally, and water drops are dropped at the starting position of the track, and the water droplets will be spontaneously transported to the end position and can smoothly pass through the transition area between the t...

Abstract

The invention belongs to the technical field of liquid self-driving transportation, and discloses a structure capable of realizing long-distance self-driving transportation of liquid. The structure used for liquid self-driving transportation is shuttle-shaped rail series structures with two sections of tangent arc in transition connections, the shuttle-shaped rail series structure is formed by sequentially connecting a plurality of shuttle-shaped rail structures with transition arcs, and a connecting position is a transition region. According to the structure capable of realizing long-distanceself-driving transportation of the liquid, and the characteristics of the liquid long-distance self-driving transportation can be realized by utilizing the effect that the liquid is subjected to laplace displacement pressure gradient on the track, so that the liquid transportation efficiency can be remarkably improved.

Description

technical field [0001] The invention belongs to the technical field of liquid self-driven transportation, and in particular relates to a structure capable of realizing long-distance self-driven transportation of liquid. Background technique [0002] Long-distance self-driven transport of liquids is the phenomenon that liquids can be transported spontaneously over long distances without external drives. It can be widely used in fields such as fog collection, microfluidic chips, and high-temperature surface cooling and heat dissipation. There are many known self-propelled transport methods for liquids. Bionic manufacturing technology is widely used in the field of liquid self-propelled transport structure preparation. For example, the structure surface imitating cactus thorns (Advanced Materials, 2013, 25(41): 5937-5942) can realize self-propelled liquid transport on the surface of the conical structure, but the liquid transport speed is slow, the transport distance is short,...
