The antibacterial double‐layered wound dressing is fabricated using chitosan (CH) film as the contact layer and tigecycline (Tig)‐loaded poly(ε‐caprolactone) (PCL) nanofibers as the top layer. The CH film has a uniform morphology, and the PCL‐Tig nanofibers show a smooth, randomly oriented, and beadless structure.
