| Abstract: | Poly(ethyl α-cyanoacrylate)(PECA) hollow nanofibers were fabricated directly by means of one-pot monomer solution casting method. The diameter of the PECA nanofibers was 50—100 nm. The whole process was simple, rapid and took place at room temperature. Three solution systems ECA/TiCl4/CHCl3, ECA/HCl/acetone and ECA/HCOOH/CHCl3 were investigated to study the influence on the morphology and size of the achieved PECA nanofibers. The mechanism of the formation of the nanofibers were proposed. By adjusting the solution system and environment, PECA with different morphology could be obtained. The PECA fibers were hydrophobic. This method not only can be used on flat surfaces, but also on surfaces with rough structures. The PECA fiber-structured coatings could offer substrates hydrophobic ability. |
