オゾン酸化反応により調製したセリア粒子を担持した布のUVカット性

摘要

Cerium oxide (CeO_(2), ceria) particles were supported on cotton and nylon fabrics by immersing the fabrics into the solution containing cerium chloride (CeCl_(3)) with bubbling of ozone (O_(3)) gas. The amount of supported ceria on the fabrics was increased with increasing of [CeCl_(3)] concentration and immersing period. Ultraviolet-visual (UV-vis) spectra of the fabrics revealed that ultraviolet (UV) shielding properties were enhanced by the supporting of the particles and the properties were kept after washing with water and SDS solution. The exposure to UV light reduced stretching strength and breaking extension of the nylon fabric supported by titanium oxide (TiO_(2), titania) particles, but they never reduced those of the fabrics supported by ceria particles.
