Effect of hexagonal boron nitride on high-performance polyether ether ketone composites

In this paper, we prepared and characterized nanocomposites of polyether ether ketone (PEEK) containing hexagonal boron nitride (h-BN) nanofiller from 1 to 5 wt%. Using various techniques, we studied the friction and wear properties, thermal conductivity, morphology, and mechanical and thermomechanical properties of the nanocomposites. Adding h-BN nanoparticles to the PEEK improved the properties of the resulting nanocomposites. At 5 wt% h-BN content, it exhibited optimum improvement of friction and wear properties, thermal conductivity, hardness, and storage modulus. Thus, we demonstrated that PEEK nanocomposites reinforced with h-BN have a great potential as multifunctional materials for future industrial applications.
