摘要

Abstract

Reversible switching from a highly rough surface to another entirely smooth surface under external stimuli is crucial for intelligent materials applied in the fields of anti-fogging

self-cleaning

oil-water separation and biotechnology. In this work

a thermal-responsive liquid crystal elastomer (LCE) surface covered with oriented micropillars is prepared

via

a facile two-step crosslinking method coupled with an extrusion molding program. The reversible change of topological structures of the LCE surface along with temperature is investigated by metallographic microscope

atomic force microscopy and optical contact angle measuring system. At room temperature

the LCE sample is filled with plenty of micropillars with an average length of 8.76 μm

resulting in a super-hydrophobic surface with a water contact angle (WCA) of 135°. When the temperature is increased to above the clearing point

all the micropillars disappear

the LCE surface becomes entirely flat and presents a hydrophilic state with a WCA of 64°. The roughness-related wetting property of this microstructured LCE surface possesses good recyclability in several heating/cooling cycles. This work realizes a truly reversible transformation from a highly rough surface to an entirely smooth surface

and might promote the potential applications of this dynamic-responsive LCE surface in smart sensors and biomimetic control devices.
