The presence of AgNPs in
the hydrophobic layer |
The hydrophilic layer had
a nonwoven structure, while the hydrophobic layer had a 3D scaffold
structure with different patterns |
The knit-like pattern of
the hydrophobic layer exhibited the best mechanical performance among
the four patterns |
The bilayer membrane had
efficient directional-water-transport performance and excellent moisture
management capability |
The bilayer membrane had
high antibacterial activity against E. coli and S. aureus due to the presence of AgNPs in the hydrophobic
layer |
These results
demonstrate
the potential of the bilayer membrane as a promising wound dressing for joint wounds |
