Abstract
Nano-fibrous carboxymethylcellulose acetate butyrate (CMCAB) mats with excellent superhydrophobicity (water contact angle 155°) were prepared by electrospinning the kind of biodegradable cellulose derivative. By analyzing the SEM image of CMCAB fibers prepared under different solvent system, it is found that the fibers have groove surface at the solvent of methylene dichloride/ethanol with the composition of 8/2 (w/w). AFM image reveal that the CMCAB mats have concave-convex surface and resembled the rough surface of lotus leaves. Hydrophobicity of CMCAB mats are strongly influenced by average diameter and surface roughness of CMCAB fiber via the determination of water contact angle. In order to improve its hydrophobicity, the effect of solution concentration and voltage on average diameter were researched and the electrospinning conditions were optimized based on the above results.
