The latest research results of natural and biological related polymeric materials are described. Synthetic polyamines, poly-methyl-L-glutamic acid (PBLG) and two natural polysaccharides, chitosan and cellulose have been successfully spun into submicron and nanofiber fibers and can be made into electrostatic Spinning nonwovens (ESNWs). The main contents are as follows: ① The relationship between the structure of PBBLG pre-spinning solution and the morphology of the resulting post-spinning and the mechanical properties of PBLG-ESNWs; ②The direct electrostatic spinning of chitosan solution, the preparation of nanofibers and the spinning of chitosan-ESNWs Treatment, both of which are related to the chemical nature of the polymer; and (3) the application of nanoscale cellulose-ESNWs in biomedical applications as a drug carrier and release material. Finally, the technical aspects of industrial applications of these ESNWs are explored, including future research questions and possible applications.
