The Effect of Incorporating Hydroxyapatite and Silica Nanoparticles in Polyethylene Surface Treatment of Natural Leather

Abstract

Leather is a natural material which is used widely in different industries. It is prone to lose moisture due to environmental conditions. Consequently, leather becomes hard and fragile, which leads to poor durability. A novel mixed system of Poly (ethylene glycol), Hydroxyapatite, plus Silica nanoparticles enhanced the mechanical, thermal, optical, and aging properties of the natural leather properties. This system also enabled the retention of moisture in leather. Thanks to the reinforcing properties of hydroxyapatite/silica nanoparticles, and the lubricating effect of poly (ethylene glycol), these modifying agents enhanced the mechanical and thermal properties of leather and preserved the leather’s natural color and gloss.
