PHOTOCHROMIC NANO FIBERS
Project no. 761 · Status: Kapanmış · 2016
Summary
The aim of this study is to obtain the photochromic dye-containing nanofiber surfaces by using the electrospinning method which will be the basis of sensor usage area and to evaluate the morphological and color properties of the obtained photochromic nanofiber surfaces. For this purpose, firstly, nanofibers were produced by using thermoplastic polyurethane at different concentrations. After the optimum concentration of thermoplastic polyurethane was determined, photochromic dye was added at different concentrations to the fiber spinning stock solution. In this context, dimethylformamide and dimethylformamide: dichloromethane solvent systems are used as solvent. The morphological and color features of the obtained photochromic nanofiber surfaces were evaluated. When microscope images of the obtained nanofiber surfaces were examined, it was observed that uniform nanofiber structures were formed. When the color change properties of the nanofiber surfaces with Ultraviolet light effect were investigated, it was seen that the coloration was not related to the photochromic dye concentration.
