The protein resistance of nanofiber membrane is low,which is easy to cause pollution and reduce the performance of the fiber membrane.Therefore,the preparation and performance of high functional polymer nanofiber membrane are studied.In the preparation of high functional polymer nanofiber membrane,the preparation condition was first determined as 15%concentration of polylactic acid solvent,and then the performance of the fiber membrane was prepared by phase transformation method.Secondly,the anti-protein property of the fiber membrane was analyzed in the experiment,and it was concluded that the anti-protein property was high.Finally,the material structure characterization of the fiber film was determined through theoretical research,the surface microstructure was observed,the porosity was analyzed,which reflected the high functionality of the fiber film.
