Abstract
In this work the effect of synergism of three components modified montmorillonite, iron nanoparticles and Tetrabromobisphenol A (TBBPA) on the flame retardancy and thermal stability of the epoxy polymer were investigated. Also for obtaining anti-bacterial property, silver nanoparticles were added to polymeric matrix. Ag nanoparticles were synthesized by ultra-sound waves (400W, 60min) in the water as a green solvent. Disk diffusion test confirm anti-bacterial activity of the silver nanoparticles against Escherichia coli and Pseudomonas. The morphology of the nanostructures was investigated by scanning electron microscopy and transmission electron microscopy. Purity and phase of the product was approved by X-ray diffraction pattern (XRD) and Fourrier transform infra-red (FT-IR) spectroscopy. Iron nanoparticles because of magnetic property have a appropriate role as a barrier against flame and oxygen and protect inner layer. Because of interaction of Fe nanoparticles and Tetrabromobisphenol A (TBBPA) , we observe long last presence of Br in the environment. Clay also is known as an effective nano-material structure for improving flame retardancy and thermal stability of the polymer matrixes. Thermal stability of the polymeric nancomposite was studied via thermal gravimetric (TGA) analysis, also flame retardancy was confirmed applying cone calorimeter, UL-94 test and limiting oxygen index (LOI) tests.
