Progress in forming of polymer microfibers and its antibacterial functional modification
Polymer microfibers have the characteristics of high specific surface area and high porosity,and have a widely application markets in medical and health protection fields such as protective clothing and masks.However,after being contaminated with pathogenic bacteria and viruses,microfibers can also become a medium for spreading microorganisms,resulting in"secondary infection".The progress of fiber electrospinning and flash spinning is introduced,and the structural characteristics of fibers prepared by different methods are analyzed;From three aspects of fiber loading natural,organic,inorganic and metal-based antibacterial materials,the antibacterial properties they endowed to fibers and their mechanism of action are analyzed.Finally,the future development of polymer microfibers is prospected.
