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