摘要:

通过溶液聚合法制备了具有空心结构的聚氰基丙烯酸乙酯纳米纤维, 纤维直径为50~100 nm. 研究了3种溶液体系对形成聚氰基丙烯酸乙酯纳米纤维形貌与直径的影响, 并探讨了其形成机理. 通过调控溶液体系内外环境可得到不同形貌的聚合物纤维, 且纤维表面表现出疏水性质. 该方法适用于平整且具有粗糙结构的表面. 所形成的聚氰基丙烯酸乙酯纳米纤维涂层可用于基底的疏水改性.

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.

Key words: Ethyl cyanoacrylate, Nanofiber, Polymer, Hollow structure
