Fractional Factorial Design to Evaluate the Synthesis and Electrochemical Transfer Parameters of h-BN Coatings

Abstract

In this study, we present a fractional factorial design approach for exploring the effects and interactions of key synthesis and electrochemical transfer parameters on the roughness and wettability of hexagonal boron nitride (h-BN) coatings, due to their essential role in biofilm formation. The studied parameters for the synthesis process include precursor mass, growth time, and substrate conditioning, whereas for the transfer process, applied voltage and aqueous medium concentration were studied. Through this polynomial model, we confirmed the strong influence of precursor mass and medium concentration parameters on h-BN surface roughness and its resulting antibiofilm properties.

Fabrication of Novel 3-D Nanocomposites of HAp–TiC–h-BN–ZrO2: Enhanced Mechanical Performances and In Vivo Toxicity Study for Biomedical Applications

“…And it also revealed attractive characteristics such as adequate inertness to body fluid, excellent biocompatibility, and greater tribological properties. − Zirconia (ZrO 2 ) is a notably important oxide material, exhibiting outstanding characteristics, including mechanical strength, osseointegration, biocompatibility, shock resistance, and thermal stability. Within diverse dental and orthopedic applications, ZrO 2 has been employed for the replacement and restoration of impaired components in the human body. , Low-density hexagonal boron nitride (h-BN), commonly referred to as white graphene, has shown significant interest due to its outstanding mechanical, optical, and thermal properties. − Among the notable characteristics displayed by h-BN, particular emphasis has been placed on its biocompatibility, bioinertness, low bacterial adhesion, and resistance to oxidation and corrosion, capturing the attention for biomedical applications of both scientific and industrial communities. ,, Therefore, TiC, ZrO 2 , and h-BN have been preferred as substitutes to develop acceptable mechanical strength as well as biological performances of pure HAp for bone implants and other biomedical applications. The wet chemical precipitation method was used to prepare the HAp powder, and HAp–TiC–ZrO 2 –h-BN composites were also fabricated via the solid-state reaction route.…”
