“…In absence of silica, the optical fiber could be attacked by photocatalysis. However, silica is chosen because it allows the passage of UV, and it is not an organic compound therefore is not degraded by photocatalysis [36].…”

“…The photocatalyst used is TiO 2 Degussa P25. Before photocatalyst coating, luminous textile needs to be protected by silica suspension (Aerodisp W7622 purchased from Evonik Degussa) as demonstrated in a previous work of C. Indermuhle et al [17].…”

Luminous textile coated by silica and TiO2 is studied for indoor air treatment. The textile aging induced by UV exposure in the presence of TiO 2 coating was studied, showing a good durability of the textile after protection by Silica layer unlike silica-free textile. Interesting photocatalytic activity was achieved for the photocatalytic luminous textile to remove three different VOCs in air which are acetic acid (AA), formaldehyde and toluene. The effect of number of photons and residence time was carefully highlighted for both TiO 2 P25 in powder or supported in the luminous textile. Then, a comparative study, between the classic system composed of TiO 2 powder and the innovative system integrating photocatalyst and light, was described. The advantage of the photocatalytic luminous textile is their performance associated to an important energy gain due to the use of one UV-LED to homogeneously irradiate an important surface of textile allowing the development of compact photocatalytic device.

“…Poly (methyl methacrylate) (PMMA) and poly (carbonate) (PC) sheets are the most common polymeric materials used in glazing [3]. However, the toughness, thermal stability and photophysical performance used to protect them against UV radiation depend on a number of both chemical and physical properties, thus it is highly desirable to improve these properties for building applications [4,5].…”

Upconverting luminescent poly(methylmethacrylate)(PMMA)/poly(urethane)(PU) interpenetrating polymer network (IPN) nanohybrids were prepared using a sequential polymerisation incorporating different wt.% of cerium phosphate (CePO 4) nanoparticles. The effect of miscibility/compatibility of the different PMMA/PU ratios, the addition and dispersion of rod and semi-spherical nanostructures in as well as the performance of selected IPNs under accelerated aging were studied using morphological, emission, thermal and mechanical studies. Structural studies revealed that there were physical interactions between C=O groups and CePO 4 in PMMA/PU IPNs. The addition of a higher wt.% of nanostructures was found to decrease the transparency of the IPNs. Resulting PMMA/PU/CePO 4 IPN nanohybrids are photoluminescent under UV-light, supporting the prolongate of lifetime while maintaining the mechanical properties after being subjected to accelerated weathering. The addition of semi-spherical particles resulted in a more stable materials after accelerated weathering than nanorods.
