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.
Claims9
Polymethylmethacrylate nanocomposite optical plastic article, comprises:
- a polymethylmethacrylate host material having a temperature sensitive optical vector x1 and nanoparticles dispersed in said polymethylmethacrylate 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 polymethylmethacrylate nanocomposite optical plastic article, comprising the steps of:
- (a) providing a polymethylmethacrylate host material having a temperature sensitive optical vector x1 and nanoparticles having a temperature sensitive optical vector x2,, wherein said temperature sensitive optical vector x1 is directionally opposed to temperature sensitive optical vector x2;
- (b) dispersing said nanoparticles into said polymethylmethacrylate host material forming a polymethylmethacrylate nanocomposite material;
- and,
- (c) forming said polymethylmethacrylate nanocomposite material into said polymethylmethacrylate nanocomposite optical plastic article.
