Abstract
abstract a retroreflective article and method is provided. the retroreflective article includes a first transparent layer having a back surface with retroreflective prisms, and a planar front surface that has an index of refraction n1. a second transparent layer having an index of refraction n2 is less than n1 overlies the back surface of the first layer. the second layer includes an array of uniform nanostructures of transparent material that define pores having a width that is less than one half of the wavelength of visible light. the nanostructures may be an array of parallel, same-sized nanorods that are obliquely oriented with respect to the first transparent layer, or a grid-like or parallel array of tapered nano-ridges of uniform size that define tapered pores or tapered grooves. the second layer preferably has a porosity greater than 60% so that the resulting index of refraction n1 is no larger than about tradução do resumo resumo patente de invenção para: "retroreflector com superfície de apoio com baixo índice refrativo" a presente invenção se refere a um artigo retrofletivo e método. o artigo retrofletivo inclui uma primeira camada transparente tendo uma superfície traseira com prismas retrofletivos, e uma superfície dianteira plana que tem um índice de refração n1. uma segunda camada transparente tendo um índice de refração n2 é menos do que n1 se sobrepõe à superfície traseira da primeira camada. a segunda camada inclui uma estrutura de nanoestruturas uniformes de material transparente que define poros tendo uma largura que é menor do que metade do comprimento de onda de luz visível. as nanoestruturas podem ser uma estrutura de nanobastões de mesmo tamanho paralelos entre si que são obliquamente orientados com relação à primeira camada transparente, ou uma estrutura em forma de grade ou paralela de nano-nervuras inclinadas de tamanho uniforme que define poros afunilados ou ranhuras afuniladas. a segunda camada preferivelmente tem uma porosidade maior do que 60% de modo que o índice de refração resultante n1 é não maior do que cerca de 1.20.
