窄分布脂肪醇聚氧乙烯醚在二氧化硅气凝胶改性中的应用性能
Application of narrow-distribution fatty alcohol polyoxyethylene ether in modification of silica aerogel
摘要
Abstract
The surface properties of industrial-grade fatty alcohol polyoxyethylene ether(AEO3)and narrow-distribution AEO3 in ethanol were analyzed,respectively.The wettability and dispersibility of hydrophobic silica aerogel in the ethanol solutions of the two kinds of AEO3 were comparatively studied.The results showed that the content of free fatty alcohol had significant influence on the wettability of hydrophobic silica aerogel in the ethanol solutions of AEO3.Then the modified silica aerogels by using two types of AEO3 were prepared,which indicated that the hydrophilicity of the modified silica aerogels could be modulated by changing the content of free fatty alcohol in AEO3 solution and the EO distribution.The higher the content of free fatty alcohol,the better the hydrophilicity;the lower the average EO addition number,the worse the hydrophilicity.The results showed that the contact angle of the silica aerogel modified with narrow-distribution AEO3 was closer to 90°.关键词
