Janus fibrous membrane with directional liquid transport capacity for wound healing promotion

A Janus membrane doped with carbon nanotubes for wet–thermal management

“…When the liquid came into contact with hydrophilic CNTs@CA bers, another CF was generated which, in combination with, HP, helped the liquid to continue to permeate, eventually allowing the liquid to penetrate the entire Janus membrane. 57,58 However, when the liquid rst made contact with the surface of the hydrophilic layer of CNTs@CA, there was strong wicking behavior due to the combined effect of CF and HP, which caused the liquid to spread across the surface. [59][60][61] Therefore, the Janus membrane with asymmetric wettability and unidirectional wicking achieved novel unidirectional liquid transport.…”

Electrospun nanofibrous membranes of recombinant human collagen type III promote cutaneous wound healing

“…37 RhCol III can be produced by fermenting genetically engineered microorganisms transfected with human genes, which results in products closer to human collagen in terms of molecular structure and properties, and suits mass production. 38 With a high porosity and surface-to-volume ratio, 39 nanofibrous materials utilized in wound treatment 40,41 possess a comparable physical structure to the natural ECM, 42,43 which expedites the regenerative process. Porous nanofibrous matrixes produced by electrospinning could mimic the ECM structure in the skin, offer a large surface area for cells, and increase the delivery of nutrients and oxygen.…”

Fabrication of Janus Composite Membranes with a Gradient Pore Structure Based on Melt Electrowriting and Solution Electrospinning for Directional Water Transport

“…Current research focuses on the development of bilayer membranes thanks to their high potential for moisture transportation by individually altering the composition and structure of each layer. , The bilayer membranes, also known as Janus membranes, are usually composed of a hydrophobic inner layer and a hydrophilic outer layer . The asymmetric wettability in the thickness direction can achieve the effect of one-way directional water transportation. − The hydrophilic layer in the Janus membrane mainly relies on a driving force to guide water transport, and the small pore size is conducive to rapid water transport (capillary transport). However, when water is transported in the hydrophobic layer, its flow resistance increases with decreasing the pore size .…”
