Abstract
An optical nanocomposite material has a nanoparticulate filler dispersed in a polymeric host photoresist material. According to the method of making the nanocomposite material, a predetermined temperature sensitive optical vector, such as refractive index, of the plastic host material and nanoparticulate filler are directionally opposed resulting in a nanocomposite material having significantly improved stability of the refractive index with respect to temperature.
Claims9
Photoresist nanocomposite optical plastic article, comprises:
- a photoresist host material having a temperature sensitive optical vector x1 and substantially transparent inorganic nanoparticles having a size less than 40 nm dispersed in said photoresist host material having a temperature sensitive optical vector x2, wherein said temperature sensitive optical vector x1 is directionally opposed to said temperature sensitive optical vector x2.
A method of manufacturing a photoresist nanocomposite optical plastic article, comprising the steps of:
- (a) providing a photoresist host material having a temperature sensitive optical vector x1 and substantially transparent inorganic nanoparticles having a temperature sensitive optical vector x2, wherein said temperature sensitive optical vector x1 is directionally opposed to said temperature sensitive optical vector x2;
- (b) dispersing said substantially transparent inorganic nanoparticles into said photoresist host material forming a photoresist nanocomposite material;
- and,
- (c) forming said photoresist nanocomposite material into said photoresist optical plastic article.
