ABSTRACT

In this research, we fabricated smart nanofibers, which have core-shell structure with thermoresponsive polymer and polyacrylonitrile by coaxial electrospinning technique for water capture and release in thermally simulated system. The microstructure and wettability of the fibers were controlled by using thermoresponsive polymer as the shell layer with varying shell thickness. The behavior of water capturing and releasing in the smart nanofibers was shown within the range of room temperature and the critical solution temperature of shell polymer. The smart nanofibers may have great potential as effective membranes for water harvesting applications.
