Title:
TRANSPARENT POLYMERIC MATERIAL WITH NANOPARTICLE DISPERSED AND PROCESS FOR PRODUCING THE SAME
Document Type and Number:
WIPO Patent Application WO/2007/129748
Kind Code:
A1
Abstract:
An organic polymeric compound/metal oxide composite composition composed of an organic polymeric compound, metal oxide nanoparticles and a polar solvent, wherein the metal oxide nanoparticles are uniformly dispersed in particulate form. The content of organic polymeric compound when the weight of metal oxide nanoparticles relative to the organic polymeric compound is constant is the content of organic polymeric compound in the composite composition composed of metal oxide nanoparticles, organic polymeric compound and added polar solvent and is not higher than critical concentration (C*). The molecular weight of organic polymeric compound is not larger than limiting molecular weight (Mc). The limiting molecular weight (Mc) when the content of metal oxide nanoparticles relative to the organic polymeric compound is a specified quantity is a value derived from the light transmittance through the composition with respect to the composition composed of metal oxide nanoparticles, organic polymeric compound and polar solvent whose addition amount is variable.
