BIOOPTICAL AND BIOFUNCTIONAL PROPERTIES, APPLICATIONS AND METHODS OF POLYLACTIC ACID FILMS

摘要

High surface energy materials with low refractive index and UV transparency wherein multilayers of similar or dissimilar materials are thermally fused together to form various functional optical requirements are provided. In some embodiments, a photocatalytic biopolymer structure comprising of a UV transparent biopolymer in integrating fused nanophotocatalytic minerals such as Tio2 used for various applications is provided. Many embodiments are based on the integration of nanophotocatalytic minerals fused to a biopolymer structure in which the biopolymer structure is UV transparent (UVT) and allows UV light to be transmitted through the biopolymer structure activating the nanophotocatalytic fused layer.

主权项

1. An ultraviolet transparent (UVT) biopolymer photocatalytic structure comprising:
a UVT biopolymer layer; a nanophotocatalytic layer in contact with the UVT biopolymer layer; and a fixed UV source positioned such that light in a uv spectra from the UV source reaches the UV transparent biopolymer layer; wherein the UV spectra can be transmitted though the UVT biopolymer structure to activate the nanophotocatatlytic layer.
