Photo-switched wettability on an electrostatic self-assembly azobenzene monolayer

摘要

A simple electrostatic self-assembly technique was used to fabricate a photo-switched azobenzene monolayer,on which superhydrophobicity and a large reversible CA change could be realized.It is known that the photo-switched trans and cis isomers of azobenzene correspond to different dipole moments and surface wettability.
