Aluminum nitride is a covalently linked substance that is a nitride of aluminum with a hexagonal crystal structure. Aluminum nitride (w-AlN) in the ferrite state is a semiconductor material with a large band gap. As a result, it can be employed in deep ultraviolet photonics as a semiconductor material.

Case 1: Thermally Conductive PVDF-Graphene Nanosheet Coating
Hydrophobic polymer coatings with high thermal conductivity are important for many reasons, such as effective surface heat dissipation in systems that heat up due to friction and as an energy conversion interface. Polymer coatings with high thermal conductivity are quite scarce and this becomes more challenging if the coating should have hydrophobic and waterproof properties.
The purpose of Alfa Chemistry's research is to create thermally conductive dense hydrophobic polymer coatings. Due to the excellent heat and chemical resistance of PVDF, we fabricated thermally conductive nanocomposite coatings from polyvinylidene fluoride (PVDF) and graphene nanosheets (GnPs), which can be effectively used as functional coatings for dynamic capture and storage of ambient thermal energy.
