The Effect of Hexagonal Boron Nitride on The Coefficient of Frictions of Organic-Inorganic Hybrid Polymer Thin Films for Metal Furface Coating
Organic-inorganic hybrid coatings were developed via a sol-gel method using hexagonal boron nitride as a ceramic filler material incorporated into a polymeric matrix. In order to investigate the effects of hexagonal boron nitride (h-BN) on the properties of polymer-based coatings, parameters such as hardness, coefficient of friction, and hydrophobicity were investigated. Colloidal silica (CS),
methyltrimethoxysilane (MTMS), water, and acid catalyst containing coatings were prepared by
varying the content of hexagonal boron nitride from 10 to 25 %. All the coatings were prepared with
the same experimental procedure and coated on 1050 aluminum alloy plates. Coatings were
examined by Fourier transform infrared spectroscopy (FTIR), scanning electron microscope (SEM),
and energy-dispersive X-ray spectroscopy (EDS).
