A novel kind of functional sutures was developed by combining electrospinning with a braiding technique. After post treatments, the electrospun PLLA nanofiber threads which were collected uniaxially were made into a more compact braided wire. Chitosan was used as a coating agent to make the braided wire surface smoothened and functionalized. Morphology and mechanical properties of the PLLA sutu...
