1Loss of energy
If inorganic nitride is mixed with organic substance to create thermally conductive material, then thermally conductive properties are improved, but dispersibility of inorganic nitride in organic substance is insufficient
Solution Approach 1:
The surface properties of inorganic nitride particles are modified by introducing organic functional groups (carboxyl, hydroxyl, amino groups) through chemical treatment. This changes the surface parameters from hydrophilic to hydrophobic character, enabling better compatibility and dispersibility in organic substances while preserving the bulk thermal conductivity of the inorganic nitride core
Solution Approach 2:
The invention creates a composite structure where inorganic nitride particles serve as the thermal conduction core, and organic functional groups form a surface coating layer. This composite approach combines the high thermal conductivity of inorganic materials with the organic compatibility needed for dispersion in resin matrices, achieving both thermal performance and dispersibility
