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.
