Abstract
An optical nanocomposite material has a nanoparticulate filler dispersed in a host plastic 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.

A reduced temperature sensitive nanocomposite optical article comprising:
- a polymeric host material having a temperature sensitive optical vector x1 and a nanoparticulate material dispersed in said polymeric 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 reduced temperature sensitive optical article, comprising the steps of:
- (a) selecting a polymeric host material having a temperature sensitive optical vector x1 and a nanoparticulate 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;
- (b) dispersing said nanoparticulate material into said polymeric host material forming a nanocomposite material;
- and,
- (c) forming said nanocomposite material into said reduced temperature sensitive optical article.
An optical plastic lens having reduced temperature sensitivity comprising:
- a plastic host material having a temperature sensitive optical vector x1 and a nanoparticulate material dispersed in said plastic 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.
