Determining Ultraviolet Degradation of High-Visibility Warning Clothing With Photochromic Indicators

Pościk A.

International Journal of Occupational Safety and Ergonomics

2013

Vol. 19, No. 1

79--86

The main purpose of this study was to select an appropriate photochromic dye and to develop a series of photochromic indicators showing ultraviolet (UV) degradation of selected background materials made from different polymers. The photochemistry of a series of photochromic compounds of oxazine and diarylethenes in thin polystyrene films were studied with spectroscopic methods. This paper also discusses the design and results of tests of UV photochromic indicators for high-visibility clothing.
