Fabrication of a superhydrophobic PET fabric using PDMS-coated SiO2 nanoparticles: Application in oil-water separation |
| 초록 |
The commercial polyethylene terephthalate (PET) and polypropylene (PP) fabric were covered with polydimethylsiloxane (PDMS)-coated SiO2 nanoparticles and they showed a water contact angle greater than 150o. The adhesion of PDMS-SiO2 was stronger on the surface of the PET than that of the PP, which was verified with scanning electron microscopy (SEM), Fourier transform-infrared (FT-IR) spectroscopy, water contact angle and water weight gain measurements. The PDMS-SiO2 coated PET (dip-PET) showed high selectivity towards selective collection of oil from the oil-water mixture, and the durable superhydrophobic properties after exposure to strong acidic/basic solutions. It was also demonstrated that the repetitive use of oil-water separation device consisting of dip-PET as the filter membrane is possible. |
