静电纺PI与PU纳米纤维膜耐消毒性能研究
Research on disinfection resistance of electrospinning PI and PU nanofiber membrane
摘要
Abstract
In order to study the influence of different disinfection methods on electrospinning nanofiber membrane,four kinds of disinfection methods including steam,75%alcohol,84 disinfection and quaternary ammonium disinfection were adopted to test the disinfection performance of polyimide(PI)and polyurethane(PU)nanofiber membranes.Their surface morphology,mechanical property,protective property and comfort performance were tested and analyzed.The experimental results showed that the fiber diameters of two fibrous membranes were both enlarged after different kinds of disinfection.After different kinds of disinfection,the breaking strength of PI nanofiber membrane was decreased and the breaking elongation rate was slightly increased.While the breaking strength and breaking elongation rate of PU nanofibrous membrane were both increased after different kinds of disinfection.The filtration property of two fibrous membranes were both decreased after disinfection treatment.After disinfection treatment,the air permeability of PI nanofibrous membrane was slightly increased,while the air permeability of PU nanofibrous membrane was decreased.The moisture permeability of the two fibrous membranes were decreased after steam disinfection while the moisture permeability of the two fibrous membranes were increased after disinfectant treatment.It is considered that under the same conditions,PI nanofibrous membranes have better disinfection resistance than PU nanofibrous membranes.关键词
