具有光致变色功能的PA6纳微米纤维的制备与性能
Preparation and properties of PA6 nano-micron fibers with photochromic function
摘要
Abstract
In order to prepare nano-micron fibers with photochromic function,the photochromic nano-micron microspheres PMMA/NA@SiO2 were prepared with naphthopyran(NA)as the color-changing unit,methyl methacrylate(MMA)as the polymer matrix monomer,and silica(SiO2)as the coating layer.Then,PMMA/NA@SiO2 nano-micron microspheres were introduced into the electrospinning solution of nylon 6.The basic morphology of PA6 was ad-justed online by optimizing each parameter in the electrostatic spinning process,and the PA6 nano-micron col-or-changing fiber with uniform diameter distribution was successfully prepared.The results of field emission SEM and UV-visible spectrophotometer show that the diameter of PMMA/NA@SiO2 ranges from 100 nm to 210 nm.When the additive amount of PMMA/NA@SiO2 is less than 10％,the morphology of the fiber sample has no obvi-ous change,and the discoloration performance is enhanced with the increase of the additive amount of discol-oration material.It leads to the best discoloration performance and morphology of sample.The prepared sample showed better discoloration and fatigue resistance after ultraviolet irradiation.It was found that the ultraviolet light of λ=254 nm has a greater influence on the color-changing performance of the photochromic nano-micron fiber compared to the ultraviolet light of λ=365 nm by ultraviolet lamp irradiation.关键词
