    公开(公告)日:2022-05-04
    Additive manufacturing processes, such as powder bed fusion of thermoplastic particulates, may be employed to form printed objects in a range of shapes. Formation of printed objects having various colors may sometimes be desirable. Thermoplastic particulates incorporating a color-changing material capable of forming different colors under specified activation conditions may impart different colors to a printed object. Such particulate compositions may comprise a plurality of thermoplastic particulates comprising a thermoplastic polymer and a color-changing material associated with the thermoplastic particulates, wherein the color-changing material is photochromic and thermochromic. Conjugated diynes, such as 10,12-pentacosadiynoic acid or a derivative thereof, may be particularly suitable color-changing materials having photochromic and thermochromic properties for forming a range of colors upon a printed object. Nanoparticles, particularly silica nanoparticles, associated with an outer surface of the thermoplastic particulates may enhance the brightness of the color obtained under various activation conditions and afford coloration permanence.

    公开(公告)日:2019-07-30
    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.
