ORGANIC-INORGANIC COMPOSITE MOLDED PRODUCT AND OPTICAL ELEMENT |
摘要 |
<p>An organic-inorganic composite molded product formed by molding a composite material of an organic resin and inorganic fine particles is provided, and in this molded product, the average primary particle diameter of the inorganic fine particles is 1 to 30 nm, the concentration of the inorganic fine particles is 25 to 50 percent by volume, and the porosity is 20 to 55 percent by volume. Accordingly, an organic-inorganic composite molded product having a small content of the inorganic fine particles and a significantly low average coefficient of linear expansion of 20*10−6 to−110*10−6/degree Celsius can be manufactured.</p> |
