Abstract

Filme óptico, filme para a difusão de luz e método de fabricação e uso do mesmo. Um método para a fabricação de um filme óptico (120) compreende aquecer o filme óptico compreendendo um percentual em peso de policarbonato maior ou igual a 80%, a uma temperatura suficiente para estirar o filme óptico, no qual o percentual em peso está baseado no peso total do filme óptico; e estirar o filme óptico, no qual um filme óptico estirado resultante apresenta um coeficiente de expansão térmica (CTE) linear, medido em uma direção paralela à direção de estiramento, menor ou igual a 50 x 10¬ -6¬ cm/cm/<198>C.
