| Outline of Final Research Achievements |
Ceramic particles having negative thermal expansion coefficient (Zr2WP2O12 and Zr2MoP2O12) were synthesized, and mixed with polyimide to prepare a polymer/ceramic composite materials having a thermal expansion coefficient of 20 ppm/K or less. First, a sintered body of Zr2MoP2O12 was prepared. And thermal and mechanical properties of Zr2MoP2O12 ceramics were estimated. Next, polymer/ceramic composites were prepared. The interface between the polymer and the ceramic particles was successfully adhered by optimizing the mixing process of the polymer precursor and ceramic particles and the polymerization process of the polymer. As a result, the thermal expansion of the polymer was effectively canceled out by the thermal shrinkage of the ceramics.
