Abstract

Synthesis and characterization of novel Tea Tree Oil (TTO) loaded antibacterial polyurethane rigid foam is reported by using two distinct methods. In the first method, the mesoporous silica used as a carrier for TTO and followed by functionalization with 3-aminopropyltriethoxysilane (APTS), for preparing of NH2- MCM-41. In the second method, the fabrication of mesoporous silica nano containers (SiO2NCs) encapsulating TTO was performed by Sol-Gel procedure, which is known to display antibacterial properties. TTO is loaded in the core of the silica Nano containers that are stabilized by surfactants as CoreShell nanoparticles (TTO@NH2-SiO2NCs). Field Emission Scanning Electron Microscopic (FESEM), Transmission Electron Microscopic (TEM), Fourier transform infrared (FTIR), Brunauer-Emmett-Teller (BET), and Thermogravimetric Analysis (TGA) analyses were used to characterize morphological, structural, and thermal properties of the prepared nanoparticles, respectively. The prepared antibacterial polyurethane rigid foams by having 2.5, 5, 7 percentages of the nanoparticles were studied by FESEM, ATRFTIR, TGA and antibacterial performance assay method, respectively. The obtained results from Viable cell count (direct contact) method was exhibited that antibacterial polyurethane rigid foam containing 7% TTO-NH2-MCM-41 has a robust antibacterial activity with >99.9% of the loss of viability for Staphylococcus aureus bacteria.
