Modified aluminum nitride, application thereof and aluminum nitride modification method
The invention belongs to the technical field of aluminum nitride materials, and particularly relates to modified aluminum nitride, application thereof and an aluminum nitride modification method. The invention provides an aluminum nitride modification method which comprises the following steps: dissolving aluminum dihydrogen phosphate, boric acid and carboxylic acid in an organic solvent to obtain a modified solution; and mixing the modified solution with aluminum nitride for surface modification to obtain the modified aluminum nitride. Under the combined action of aluminum dihydrogen phosphate, boric acid and carboxylic acid, aluminum nitride and oxygen-containing functional groups such as hydroxyl on the surface of the aluminum nitride react to form a compact protective layer, so that the aluminum nitride is prevented from being in direct contact with water; meanwhile, a protective layer formed under the combined action of aluminum dihydrogen phosphate, boric acid and carboxylic acid has strong binding force with aluminum nitride, can exist for a long time under the high-temperature condition of 85 DEG C, does not fall off and improves the high-temperature hydrolysis resistance of the modified aluminum nitride.
本发明属于氮化铝材料技术领域，具体涉及一种改性氮化铝及其应用、氮化铝改性方法。本发明提供了一种氮化铝改性方法，包括以下步骤：将磷酸二氢铝、硼酸和羧酸溶解于有机溶剂，得到改性溶液；将所述改性溶液和氮化铝混合进行表面改性，得到改性氮化铝。本发明在磷酸二氢铝、硼酸和羧酸共同作用下与氮化铝及其表面的羟基等含氧官能团反应形成致密的保护层避免氮化铝直接与水接触；同时在磷酸二氢铝、硼酸和羧酸共同作用下形成的保护层与氮化铝具有较强的结合力能够在85℃的高温条件下长期存在，不发生脱落提高了改性氮化铝的高温耐水解性。
