摘 要: | 通过氟硅单体1,3,5-三甲基-1,3,5-三(3,3,3-三氟丙基)环三硅氧烷(简称F3)的阴离子开环聚合(ROP)、苯乙烯(St)的原子转移自由基聚合(ATRP),合成了含氟硅嵌段共聚物PMTFPS-b-PS,并将其以四氢呋喃(THF)和N,N-二甲基甲酰胺(DMF)为溶剂进行静电纺丝。采用接触角测量仪(CAM)、扫描电镜(SEM)、X射线光电子能谱(XPS)研究PMTFPSb-PS电纺膜退火前后的疏水性、微观形貌以及表面化学组成。结果表明:电纺纤维的水接触角可达152.6°,即达到超疏水的效果,经过120℃退火处理后电纺膜的表面光滑,接触角有所减小,但其水接触角仍远高于共聚物溶剂膜的接触角。

Abstract: | This study synthesizes fluorosilicone contained segmented copolymer PMTFPS-b-PS through anion ring opening polymerization(ROP)of fluorosilicone monomer 1,3,5-trimethyl-1,3,5-three(3,3,3-trifluoride propyl)trisiloxanes(F3)and atom transfer radical polymerization(ATRP)of styrene(St),conducts electro-spinning with tetrahydrofuran(THF)and N,N-dimethylformamide(DMF)as solvents and studies the hydrophobicity,microstructure and surface chemical constitution of PMTFPS-b-PS electro-spinning film before and after annealing through contact angle meter(CAM),scanning electron microscope(SEM)and X-ray photoelectron spec(XPS).The result shows that water contact angle of electro-spinning fiber can reach 152.6°,i.e.achieve super-hydrophobic effect;electro-spinning film subject to annealing at 120℃has a smooth surface and its contact angle decreases,but its water contact angle is still higher than the contact angle of copolymer solvent membrane. |
