本論文探討高導熱氮化鋁/環氧樹脂和氮化硼/環氧樹脂複合材料的製程結果。氮化鋁複合材料部分，針對模具種類和複合材料熱壓前的造粒方式進行研究。本論文主要使用之新模具和實驗室往年常用之舊模具相比，前者可以提供複合材料較密實的受壓，在粉體未改質的條件下，新模具做成之複合材料熱擴散優於過往實驗室之經驗。本論文採取較大的造粒粒徑手法，搭配新使用的模具下，偶合改質劑對氮化鋁複合材料熱擴散改質效益優於過往實驗室之各種舊模具及造粒手法數據，且支持去年實驗室發現造粒粒徑過小會不利於氮化鋁複合材料改質劑效益之觀察，而本論文新發現氮化硼複合材料之改質效果亦有此現象。而對於無改質之氮化鋁粉體做成複合材料本身，本論文新發現較小之造粒粒徑手法，氮化鋁複合材料熱傳性質卻反而較佳，氮化硼複合材料亦有此現象。氮化硼複合材料部分，對於實驗室自製氮化硼粉體，比較不同酸洗配方及酸洗條件下，酸洗後之粉體做成複合材料之結果，由結果顯示，混合鹽酸與硝酸之配方比起僅使用鹽酸，而酸洗溫度在攝氏50度比起在室溫下酸洗，酸洗過之粉體做成複合材料熱傳性質較佳。

This paper discusses process development for AlN/epoxy and BN/epoxy high thermal conductivity composite materials. The AlN/epoxy composite material part, use different molds and granulation methods before thermal compression as experiment parameters. The paper use the new mold compares to the old molds in lab, the former mold provide composite more uniform compression. Using the AlN powder without surface modification to make composite, the one using new mold has higher thermal diffusivity compared to past lab’s experience; Using the powder after surface modification to make composite, the one using new mold has higher thermal diffusivity enhancement by big granulation method compared to past lab’s experience by any other molds and granulation methods .The result support the corollary that the too much small granulation method will disable the surface modification for thermal diffusivity enhancement. And this paper newly find that the BN composite material has the above surface modification phenomenon. Using the AlN and BN powder without surface modification to make composite, this paper newly find that small granulation method get higher thermal diffusivity. For the BN/epoxy composite material part, using the powder made by our lab, compare that after different acid washing conditions then making composie and observing its thermal diffusivity. This paper newly find that using mixed acid containing nitric acid and hydrochloric acid condition is better than single hydrochloric acid condition and the acid washing condition in 50 degrees centigrade is better than room temperature.
