基于AIE聚合物的荧光复合纤维制备及性能研究
Preparation and property research of fluorescent composite fibers based on AIE-active polymers
摘要
Abstract
In order to reduce the influence of fiber matrix on the luminescence characteristics of flu-orescent dyes,fluorescent fibers with excellent fluorescence and luminescence stability were prepared by wet spinning using AIE active fluorescent polymers(FP-1 and FP-2)as additives and thermoplastic polyurethane(TPU)and polyacrylonitrile(PAN)as polymer matrices.The chemical structures,optical properties,and mechanical properties were characterized via 1H NMR,GPC,SEM,UV-Vis,and PL.The results indicate that the PMMA molecular chains in FP-1 and FP-2 not only restrict the intramolecular rotation of the fluorophores but also prevent their close contact through physi-cal isolation,thereby enhancing the luminescence efficiency of the fluorescent polymers.When the addition amount of FP-1 and FP-2 in the fiber matrix is only 1.0％,the prepared fluorescent fibers exhibit excellent luminescence performance(yellow and red fluorescence).Moreover,the PMMA chain forms a hydrophobic microenvironment within the fiber matrix,and simultaneously forms molecular chain entanglements with the fiber polymer matrix,thereby enhancing the luminescence stability.Due to the low addition amount of the fluorescent polymers and their uniform dispersion in the fiber matrix,the addition of the fluorescent polymers does not affect the mechanical proper-ties of the fibers.The prepared fluorescent TPU fibers have excellent fluorescence performance,good tensile and flexibility,and certain application potential in functional textiles.关键词
