Preparation of superhydrophobic surface on P(VDF-HFP) fibers by electrospinning technique

Abstract

In this work, a superhydrophobic surface of poly (vinylidenefluoridene-hexafluoropropylene) (P(VDF-HFP)) fibers was fabricated by means of electrospinning technique. The effects of flow rate on the morphology and hydrophobicity of P(VDF-HFP) nanofibers were investigated by scanning electron microscopy (SEM) and water contact angle (WCA), respectively. The results exhibit a uniform P(VDF-HFP) fiber mat at the lowest flow rate. However, the presence of bead-on-string the fibers was exhibited at higher flow rate. The average fiber diameter of P(VDF-HFP) fibers is increased with increasing flow rates. The WCA values of the P(VDF-HFP) fibers with bead-on-string structure could reach up to 158.60°, indicating as the superhydrophobicity. These as-received porous P(VDF-HFP) fibers with superhydrophobic surface are attractive properties for self-cleaning materials used for further several industrial applications.

“…Similarly, the electrospinning method is also suitable for preparing superhydrophobic textiles of small sizes. 69,70 Yuennan et al 71 fabricated superhydrophobic poly (vinylidenefluoridene-hexafluoropropylene) (P(VDF-HFP)) fibers by using an electrospinning technique. The WCA values of the P(VDF-HFP) fibers could reach up to 158.6 .…”

“…Among these techniques, superhydrophobicity plays a key role in downstream applications; therefore, considerable efforts have been made in recent years to prepare superhydrophobic materials for various purposes in recent years. [15][16][17][18][19][20][21] It is well known that a low surface energy and micro/nanostructural roughness are the important aspects to prepare superhydrophobic surfaces. Therefore, there are so many methods and researches on the preparation of superhydrophobic materials.…”
