Hydrophobic-hydrophilic Janus water collection membrane and efficient preparation method thereof
PendingCN120139328ASynthetic resin layered productsCellulosic plastic layered productsSpinningHydrophobic polymer
The invention discloses a hydrophobic-hydrophilic Janus water collecting film and an efficient preparation method thereof, and belongs to the field of water collecting materials. An electrostatic spinning process is adopted, and a hydrophobic polymer is accurately deposited on the surface of a hydrophilic substrate in the form of a nanofiber array, so that the Janus composite membrane with an asymmetric wetting gradient structure is successfully constructed. The unique double-sided wettability difference drives the liquid drops to realize directional transmission, and the core mechanism of the liquid drops is derived from capillary force regulation and control caused by interfacial wetting potential energy difference. The Janus membrane shows excellent performance in the aspect of air moisture trapping, the ultra-fast moisture absorption characteristic and the surface regeneration capacity are achieved, and compared with a traditional single-layer hydrophilic membrane, the water collecting efficiency is remarkably improved by 110%. A one-step forming process is adopted for preparation, the diameter of the nanofibers is controllable, complex post-treatment procedures are not needed, and energy consumption required by equipment is low. The high-performance water collecting film has important application value in the fields of atmospheric water taking in arid regions, dehumidification of precise instruments and the like.
