  • Diacetylene film sensitized with photoinitiator and applications of the film
    Patent number: 10365154
    Abstract: A process for improving sensitivity of a film base, coated with a dispersion of a normally crystalline polyacetylenic compound in a non-solvating liquid which is dried on the film surface, to particular photon energy band, specifically, long wavelength UV; the polyacetylenic compound preferably having at least two conjugated acetylenic linkages and containing from 12 to 60 carbon atoms. The sensitization of the film to long wavelength UV is achieved via the addition of photoinitiator(s) capable of absorbing UV energy and converting it to free radicals. The process comprises dispersing the normally crystalline polyacetylenic compound in the non-solvating liquid to a concentration of from about 2 to about 50% polyacetylene crystalline solids and a photoinitiator or combination of photoinitiators to a concentration of from 0.01 to 10%. The resultant dispersion is then coated and dried on a substrate. Additionally, applications using this film as a UVA illumination indicator and dosimeter are disclosed as well.
