疏水材料构筑亲水性核壳结构超细纳米纤维膜与流体过滤性能
Hydrophobic Materials Constructing Hydrophilic Core-shell Structured Ultrafine Nanofiber Membranes and Fluid Filtration Performance
摘要
Abstract
To solve the existing issues of hydrophobicity and large fiber diameter in hydrophobic substrate PVDF for water filtration,the hydrophilic core-shell structured ultrafine nanofiber membranes were prepared in one step by the electrospinning mutually repulsive splitting method and technology.Through tests of the fiber membrane's conductivity and viscosity,chemical groups,diameter and pore size distribution,hydrophilicity/hy-drophobicity properties,TEM test and filtration performance,the results demonstrated that when the contents of cetyltrimethylammonium bromide(CTAB)and tetrabutylammonium chloride(TBAC)were both 1 wt%,the fi-ber diameter reached a minimum of 87.01 nm,hydrophilicity significantly improved with a water contact angle of 23.98°,the fiber membrane pore size was as low as 0.61 μm,achieving a filtration efficiency of 99.26%for submicron particles and efficiency exceeding 99%for 0.3 μm particles.关键词
