Fabrication and Characterization of Photochromic Spirooxazine/Polyvinylidene Fluoride Fiber Membranes via Electrospinning

“…In recent years, photochromic materials have been widely applied in protective ophthalmic lenses, security printing, optical memory and switching, solar energy storage and electrophoretic displays [1,2] because they can change from colorless to colorful when exposed to UV light but can become colorless again after the UV light is removed [2][3][4][5]. Among photochromic materials, spirooxazines have received considerable attention due to their intense photocoloration [6][7][8], fatigue resistance and ease of synthesis [9][10][11].…”

“…knowledge, few reports have focused on the design of SPF membranes by electrospinning. [1,4] oxazine] was synthesised. Spirooxazine was characterised by means of FTIR and UV spectrophotometers, and SPF membranes with different contents of spirooxazine were prepared by the electrospinning technique, followed by FTIR and SEM characterisations.…”

Innovative Molecular Design for a Volume Oriented Component Diagnostic: Modified Magnetic Nanoparticles on High Performance Yarns for Smart Textiles

“…Such materials are especially suited for the volume production of complex lightweight components and thus contribute to minimize energy consumption in automotive and mechanical engineering. [6,7] The goal of the work presented here was therefore to develop a volume-based structural testing for applications in the lightweight engineering based on functionalized textiles. [2][3][4] However, the non-destructive testing methods commonly used (e.g., metallic materials) cannot directly be applied to lightweight plastic composites and new testing procedures have to be developed.…”
