尼龙织物超双疏涂层的制备及其自清洁研究

摘要

用丙烯酸六氟丁酯(HFBA)和含双键的硅树脂(SR)进行乳液共聚,以该共聚乳液对尼龙织物进行浸涂,制备出超疏水和超疏油的尼龙织物.对织物进行了红外光谱、扫描电镜分析,并研究了单体配比、浸涂次数和织物种类对织物超疏水性能和超疏油性能的影响.实验结果显示,单体质量比SR∶HFBA=5∶18,乳液浸渍3次,可以使尼龙织物表面获得超双疏性能,对水和油的接触角分别可达到152.25°和155.69°.该织物还具有较好的自清洁性能.%Copolymer emulsion was prepared by copolymerization of HFBA and SR,and was coated on Nylon fabrics.The obtained superamphiphobic coating fabric was characterized by IR and SEM.The influences of the monomer mass ratio,the emulsion dipping times and the fabrics type on the superamphiphobic property of the Nylon fabrics were studied.The experimental results showed that the Nylon fabric surface achieved superhydrophobicity and superoleophobicity when the monomer mass ratio and the emulsion dipping times were 5∶18 and 3 times.The water contact angle and oil contact angle were 152.25° and 155.69°,respectively.The fabrics obtained good self-cleaning performance.
