摘要

采用自由基聚合法将共聚物接枝到多壁碳纳米管(MWCNT)上制备超疏水表面。结果表明

以

-甲基苯乙烯(AMS)与甲基丙烯酸丁酯(BMA)为单体

经自由基聚合可得到共聚物AMS-

-BMA(PAB)

其热降解产物接枝到MWCNT表面可制得与水滴静态接触角为165°

滚动角小于3°的超疏水表面。SEM分析结果表明

共聚物的接枝一方面增大了管间的空隙

增加了表面粗糙度

另一方面又为降低表面能提供了条件。不同pH值液滴测试及放置时间的影响结果表明

该超疏水表面具有较好的稳定性和耐久性。

Abstract

A superhydrophobic surface was fabricated by grafting the copolymers onto multiwalled carbon nanotubes (MWCNT) using free radical polymerization. The results showed that

-methylstyrene and butylmethacrylate can prepare copolymers PAB

and the thermal degradation products can graft onto MWCNT to obtain superhydrophobic surface with maximum static water contact angle of 165° and sliding angle of less than 3°. The result of SEM indicated that grafting copolymers increased the gap between tubes and roughness of surfaces

and provided conditions for decreasing surface energy. Droplet test of different pH value and the effect of exploring time showed that the prepared surfaces have excellent stability and durability.
