Employing Nano-Titanium Dioxide Laser Coating in Local Materials used in Interior Spaces, Palm Leaves (Barhi) Model

Abstract

Nanotechnology is considered one of the most important modern technologies used in interior design, which has contributed to improving the specifications of the materials used and their applications. The research problem can be summarized in the following question: What is the importance of employing nano-titanium dioxide laser coating in local materials used in interior spaces? The research aims to use nano-coating as a means to improve the specifications of palm leaves used in the interior designs of some traditional Iraqi homes and cafes. Given that titanium dioxide (Tio2) is a compound with good properties, being a non-toxic, cheap and stable substance in addition to having optical properties, titanium dioxide was used in this study to coat palm leaves (Barhi) and deposit them with different thicknesses by pulsed laser deposition, which is considered a deposition method. It is fast and suitable for producing homogeneous layers of different thicknesses on the materials to be coated. The results showed that the use of titanium oxide nanoparticles increased the resistance and durability of the paper compared to uncoated paper. Laser coating also contributed to controlling the thickness of the nano-coating layer.

Increasing the thickness of the nano-coating layer leads to an increase in the resistance of the Barhi palm leaf to the compressive forces applied to it. The maximum endurance strength of the leaf coated with titanium dioxide through the experiments of this research was (14 KN) with a nano-thickness of (195) nanometers.
