| Abstract: | Superhydrophobic silica aerogels are prepared by sol-gel reaction and ambient pressure drying(APD)under the action of cetyltrimethylammonium bromide(CTAB),using methyl trimethoxy silane(MTMS)as silicon source and water as solvent.Silica aerogel powder and polydimethylsiloxane(PDMS)are applied to cotton fabric by spraying method.The structure,morphology and hydrophobicity of the cotton fabric are characterized by scanning electron microscope,infrared spectrometer and contact angle measuring instrument.The results show that the prepared silica aerogels have typical three-dimensional network porous structure and super hydrophobic properties.The finished cotton fabric(PDMS/SiO2@cotton fabric)exhibits super hydrophobic properties with 161.1°of water contact angle(WCA),good anti adhesion,self cleaning and anti fouling properties. |
