Abstract: Four different cationic surfactants were allowed to adsorb on boron nitride (BN) over the pH range of 5.5 to 8 in separate experiments. The authors talk about the orientation of the surfactant relative to the BN particles. The use of these surfactants has changed the partial ionic surface of BN to a hydrophobic surface, which also led to an increase in thermal conductivity and more favourable mechanical properties.
