Thermal extrusion method to fabricate large-dimension superhydrophobic cylinder pillar arrays with droplet pancake bouncing phenomenon

A thermal extrusion method to fabricate large-dimension superhydrophobic cylinder pillar arrays with droplet pancake bouncing phenomenon. Preparing thermal extrusion mold: the through-hole arrays with 0.8˜1.25 mm diameter, 0.25 mm interval space and 0.6˜1.0 mm height are first obtained on metals, and are then polished, rinsed and dried. Thermal extrusion: polymer materials are first thermally extruded on the obtained mold and cooled to room temperature. Demold: excess polymer materials flowing from the through hole are cut off and then the polymer cylinder pillar arrays are lifted off from the mold. Superhydrophobic treatment: the whole polymer sample is treated using mixed liquid spray consisting of titanium oxide nanoparticles dispersed in fluoroalkylsilane ethanol solution, and the superhydrophobic cylinder pillar arrays are obtained. The method is easy to operate, low-cost, recyclable, effective for different polymer materials, and can obtain cylinder pillar arrays with large dimensions, which can realize efficient large-area and industrial fabrication of the droplet pancake bouncing surfaces.
