摘　　要：采用无皂乳液技术合成了自修复纤维素纳米晶改性含氟聚丙烯酸酯无皂乳液,并将乳液用于织物整理。研究了不同丙烯酸十八酯(SA)用量下的乳胶粒粒径、乳胶膜的疏水疏油性、力学性能和自修复性能,以及整理织物的疏水疏油性和自修复性能。结果表明:当SA质量分数为1.0%时,乳胶粒粒径较小,水/油接触角分别为104.35°和70.25°,拉伸强度为4.17 MPa,断裂伸长率为720.88%,自修复效率为91.49%,表现出良好的疏水疏油性、力学性能和自修复性能。经乳液整理的织物水/油接触角分别为150.70°和127.40°,呈现出优异的疏水疏油性,以及较好的划痕和表面疏水性的自修复性能。The self-healing cellulose nanocrystal modified fluorinated polyacrylate soap-free emulsion is synthe⁃sized by soap-free emulsion polymerization,and is used for fabric finishing.The latex particle size of the emul⁃sion,hydrophobicity,oleophobicity,mechanical properties and self-healing properties of latex film,as well as hydrophobicity,oleophobicity and self-healing properties of the finished fabrics are investigated at different concentrations of octadecyl acrylate(SA).The results show that when the SA concentration is 1.0%,the latex particle size is small,the water/oil contact angles are 104.35°and 70.25°,respectively,the tensile strength is 4.17 MPa,the elongation at break is 720.88%,and the self-healing efficiency is 91.49%,which show good hydro⁃phobicity,oleophobicity,mechanical properties and self-healing properties.The water/oil contact angles of the finished fabrics are 150.70°and 127.40°,respectively,showing excellent hydrophobicity and oleophobicity,as well as better self-repairing properties for scratches and surface hydrophobicity.
