Abstract
The effects of the incorporation of a phosphate glass micrometric powder on the morphology, as well as on the thermal, optical, mechanical and flame retardant properties of UV-LED curable acrylic films are thoroughly investigated. To this aim, the filler loading was changed within 10 and 50 wt.%. The glass powder slightly increased the glass transition temperature (Tg) of the acrylic network; besides, increasing filler loadings were responsible for a progressive decrease of the transparency of films, irrespective of a marginal effect on their refractive index. Conversely, the presence of increasing amounts of phosphate glass improved the thermal and thermo-oxidative stability of the cured products, as well as their flame retardant properties.File | Dimensione | Formato | |
