Dependence of the photodegradation rate on the crystalline portion of PE films obtained through in situ polymerization in the presence of TiO2 nanospheres, nanoribbons and microspheres

Effect of anodisation time and thermal treatment temperature on the structural and photoelectrochemical properties of TiO2 nanotubes

“…Therefore, TiO 2 based materials have been widely applied in dye sensitised solar cells, hydrogen production, the degradation of dyes and polymers [4][5][6][7][8][9]. In porous films of nanostructured semiconductors, the electronic transport is carried out through random pathways, by hopping from one nanoparticle to another, finding several energy barriers as grain boundaries and surface states, which causes the overall system conductivity to be very slow.…”

Aging Effects on the Mechanical Performance of Carbon Fiber-Reinforced Composites

“…On exposure to direct sunlight, the polymer composite reacts with photons of UV rays, and then the crosslinking of macromolecules gets affected, hence degrading mechanical and physical properties, as shown in Figure 4 [64]. These rays are destructive to the composite material and initiate the chain scission process International Journal of Polymer Science [65]. Then, chain scission at the polymer surface causes microcrack formation, diminishes color, and leads to covalent bond breakage, hence decreasing the weight of the composite structures [66].…”
