Nanofiber multifilament (NFMF) made by CO2 laser supersonic multi-drawing (CLSMD).
Continuous PLLA-NFMF can be prepared by CLSMD.
PLLA-NFMF obtained was composed of approximately 85,000 NFs with an average diameter of 0.311 μm.
NFMF braid could be prepared with a braiding machine.
CLSMD is a green process for the preparation of NFMF composed of various polymers without the use of a solvent.
