Property Characterization of Ionic Liquid Modifying Silica
摘要
Abstract
Ionic liquid 1-allgl-3-methylimidazolium chloride ( AMI ) was employed to modify silica .The microstructure and property of silica of modification before and after were characterized with Fourier transform infrared spectroscopy ( FT-IR ) , X-ray diffraction ( XRD ) , X-ray photoelectron spectroscopy ( XPS ) , Thermal gravimetric analysis ( TGA ) , Scanning electron microscope ( SEM ) , contact goniometer, BET specific surface area and pore diameter analysis .The result shows that , through AMI modification, interaction of silica particle decrease obviously , agglomeration between the particles weak , dispersion property improve evidently in rubber composite matrix , hydrophobic property of modified silica enhance, the range of contact angle increase from 12.7°to 80.5°.Specific surface area aggrandize from 67.84 cm2/g to 124.28 cm2/g.Modification before and after, the crytalline structure of silica change little, yet amorphous structure .关键词
