successfully fabricated by employing the water coalescence induced self-assembly of nanopfragments attached on the fiber. The sizes and distances of the humps on BWMF are
10 easily controlled by regulating coalescence time and relative humidity. Furthermore, an excellent BWMF is obtained to be contributed to strong water collection. This finding is
significant to fabricate smart materials with homo- or heterostructures at micro- and nano-level that can beextended into realms such as microreactor, sensor, fogharvesting
and others.
