Want to mix aluminum nitride (AlN) filler, a high-thermal-conductivity ceramic powder, into epoxy resin to make thermally conductive materials? Simply blending them in often yields disappointing results. The crucial step is: surface treatment of the AlN fillers is essential.
What happens if aluminum nitride (AlN) filler WITHOUT surface treatment in Epoxy Resin??
Agglomeration: AlN particles clump together, failing to disperse evenly in the resin.
Poor thermal conductivity: Due to clumping, an effective heat-transfer network cannot form, limiting heat dissipation.
Weak bonding: Fillers and resin don't adhere well, making the composite prone to cracking under stress or heat.
Benefits after treatment:
Excellent dispersion: Particles separate nicely and distribute uniformly in the resin.
High thermal conductivity: A continuous and efficient heat-transfer pathway is established, fully utilizing AlN's high thermal conductivity.
Strong adhesion: Tight bonding with the resin makes the material more robust and durable.
Enhanced stability: The treated surface resists moisture, preventing AlN from degrading and ensuring long-lasting performance.
