Synthesis of Magnesium Oxide Nanoparticles for Fabric Coating and its Antibacterial Activities

Abstract

Conceptually, the present work leads to the synthesis of magnesium nanoparticles (MgO NPs) using pomegranate (Punica granatum L) rind extract for antibacterial fabric coating. The antibacterial performance of MgO NPs on cotton, polyester and blend wool types of fabric was evaluated towards three species of gram-positive bacteria; Staphylococcus epidermidis, Brevibacterium linens and Cutibacteriumacnes. Fourier transform infrared spectroscopy (FTIR) analysis confirmed the successful of sol-gel synthesis process with the presence of flavonoid compounds in MgO NPs solution. The breaking load test was run for all fabric samples, while for tearing strength test, it was carried out only for cotton and polyester fabrics. Air permeability test device was used to determine the air permeability of all fabric samples to ensure the ventilation of the fabrics after coating process. The MgO NPs produced from sol-gel synthesis method established a good antibacterial activity against gram-positive bacteria in all types of fabric samples.
