Synthesis and characterization of antibacterial polyurethane rigid foam nanocomposites by incorporation of tea tree oil as a natural biocide

Synthesis and characterization of novel Tea Tree Oil (TTO) loaded antibacterial polyurethane rigid foams using two distinct methods is reported. In the first method, 3-aminopropyltriethoxysilane (APTS) functionalized mesoporous silica was used as carrier TTO for preparing amino-functionalized (TTO-NH2-MCM-41). second one, encapsulated by via sol-gel then APTS, nanocontainers with amino groups ([email protected]2-SiO2NCs), which known to display properties. Field Emission Scanning Electron Microscopic (FE-SEM), High-Resolution Transmission (HRTEM), Fourier transform infrared (FTIR), Brunauer-Emmett-Teller (BET), Thermogravimetric Analysis (TGA) analyses were characterize morphological, structural, thermal properties prepared nanoparticles, respectively. The foams, had 2.5, 5, 7 percent synthesized characterized FE-SEM, ATR-FTIR, TGA, performance assay methods, obtained results from viable cell count (direct contact) method exhibited that foam containing % TTO-NH2-MCM-41 has a robust activity > 99.9 reduction bacteria (>4 Logarithmic reduction) Staphylococcus aureus bacteria.
