- Abstract：This review summarized the preparation principle，processing，functionalization and related research progress
of the thermoplastic nanofibe~，on the basis of the new environmentally benign technique—melt extrusion phase separation
method invented by the corresponding author．This high—throughput，controllable fabrication process of thermoplastic nano·
fibers with a biobased material，cellulose acetate butyrate(CAB)as the matrix was introduced．The specific functionalization
methods of nanofibers and nanofibrous membranes，including radical graft polymerization，SI·ATRP，and click reac—
tion were illuminated．The research progress on the application in biosensor，antibacterial materials，filtration and separa—
tion，and anti—fouling materials of nanofibers and naofibrous membrane were emphasized．New functional materials or ap·
pliances were developed，including nanofibers based sensors with synergistic functions of rapidly detecting and eliminating
biohazards，antibacterial nanofibrous membranes，high eficient nanofiber membranes applied in water filtration and heavy
metal ion removal，nonspeeifie protein resistant and photoinduced self-cleaning nanofiber membrane．The key problems for
developing functional nanofibe~ and the importance were discussed．Finally，the promising research direction and the ap—
plication fields were pointed out．
