摘要
文中以聚酯纤维(PET)为原料,通过针刺工艺制备了PET非织造材料,然后采用液相沉积法在PET纤维表面原位生长硅纳米线(SiNFs),构建了具有微纳双阶粗糙结构的过滤与分离材料(SiNFs@PETs),并对其结构和性能进行了表征。结果表明,经过液相沉积,PET纤维表面粗糙度增加,且在纤维表面分布均匀;延长沉积时间,制备了不同微观结构的纳米硅沉积物(棒状-卷曲状-粒子链状)。另外,表面改性赋予材料超疏水性能(170.2°),且提升了材料的空气过滤性能(对1.0μm颗粒的过滤效率提升了260%)和油水分离效率(>90%),在空气过滤与油水分离领域呈现出较大的应用优势。
Herein,the polyester(PET)nonwoven was firstly prepared by needle-punching process using PET fibers as raw materials.And then,a novel one-step in situ method was introduced to grow silicon nanofilaments(SiNFs)on the surface of PET fibers through liquid phase method,constructing filtration and separation materials with micro-nano dual-stage rough structure.The results are as follows.Different rough structures emerge and a transformation from nanorods to nanofilaments is observed during the liquid deposition process.Moreover,the in situ hybrid material shows super hydrophobic properties(water contact angle in the air is 170.2°),extremely high efficiency air filtration function(the increase in filtration efficiency for PM1.0 by 260%),and excellent oil-water separation efficiency(>90%),showing promise as a potential solution for large-scale air filtration and oil/water separation.
