In
nature, the water-repellent surface of a superhydrophobic material
such as lotus has the micro/nano hierarchical structure, while shish-kebab,
which is one of the most fascinating superstructure crystals in polymer
science, also exhibits micro/nano hierarchical structure. Accordingly,
it remains an idea of whether this structure can be used as the superhydrophobic
materials. In this work, a modified flow-induced crystallization method
was employed to fabricate a pure shish-kebab membrane, whose wetting
behavior and other related performances were comprehensively studied.
The membrane surface displays superhydrophobic characteristic with
a static water contact angle of 161° and sliding angle of 3°.
More importantly, the superhydrophobic membrane not only is of low
adhesive, anti-impact, and self-cleaning performance, but also presents
oil/water separation capacity, high absorption capacity with porosity
(67–83%), and recyclability for organic liquids. This work
proposed a new approach from the viewpoint of shish-kebab aggregation
to construct a micro/nano structure in the polymer membrane with superhydrophobicity
and other functional properties.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
