摘要
利用1H,1H,2H,2H-全氟辛基三氯硅烷对SiO_2纳米粒子进行表面改性,制备得到氟硅改性SiO_2纳米粒子(M-SiO_2),并将其与聚对苯二甲酸乙二酯(PET)共混后溶于六氟异丙醇(HFIP)溶剂中进行静电纺丝。采用接触角测量仪、扫描电镜和X射线光电子能谱研究了M-SiO_2/PET电纺膜的疏水性能、表面形貌以及化学组成。结果表明,静电纺丝法制备的M-SiO_2/PET共混电纺膜对水的接触角可高达155.2°,并且对水的滞后角仅为3.4°,即具有超疏水性能。
M-SiO2 nanoparticles were prepared from silica modified with 1H, 1H, 2H, 2H- perflurooctyltrichlorosilane, and then blended with polyethylene terephthalate （PET） in 1,1,1,3,3,3-hexafluoro-2- propanol （HFIP）. The blend electrospun films of M-SiO2/PET were obtained via an electrospinning process and the surface hydrophobility, microstructure and chemical composition were studied through contact angle meter （CAM）, scanning electron microscope （SEM） and X-ray photoelectron spectroscope （XPS） measurements. The results show that the water contact angles of electrospun M-SiO2/PET films could reach 155.2°, and the water hysteresis angle is only 3.4°, demonstrating the superhydrophobic performance.
