摘要
The facile fabrication of superhydrophobic membrane with patterned and controllable wettability is crucial to the exploitation of precise control of water flow path. Here, an azobenzene-bridged bipedal pillararenes-crosslinked polypseudorotaxane is used to fabricate a superhydrophobic membrane via the combination of electrospraying and breath figure approaches. Regulation of the relative humidity during electrospraying process and the trans-cis isomerization of azobenzene provide the capability to control the water adhesion force of membrane. These rules are applied to engineer the wettability of membrane into various patterns via re-electrospraying or light irradiation with patterned photomask. These efforts demonstrate the potential of polypseudorotaxanes for applications in smart membrane with patterned wettability.
