Abstract

The precise control of fluid transport is of significant importance in intelligent systems and microfluidics. However, current research typically involve either the directed transport of a single type of fluid or requires complex preparation processes. This work utilities the complementary superwetting surface of polyimide/Poly tetra fluoroethylene to achieve the spontaneous directional transport of water droplets and underwater bubbles through single femtosecond laser processing. This technology enables the preparation of flexible and diverse structures for complex fluid control. This work presents a novel approach to the control of fluid transport, with a multitude of applications in aerospace, medical and intelligent transportation.
