Fabrication, development and industrial applications of flame retardant polymeric nanocomposite materials for battery systems

Nowadays, polymers are used industrially in many fields such as automotive, electronics and decoration. However, it is known that these materials, which have such a wide range of use, have advantages as well as their low resistance to fire. In addition to this, the use of eco-friendly halogen free flame retardant additives, which are not harmful to health, is also increasing. In this study, it is aimed to produce, develop and apply to industry flame retardant additives by adding flame retardant additive into polypropylene matrix. For this purpose, additives such as halogen free antimony oxide, bentonite, zinc borate and huntite hydromagnesite are used in single, double, triple and quadruple compositions to determine the best flame retardant mixture composition. The size of the additive materials has been reduced to nano size as it is thought to provide better flame retardant properties. While the flame retardant property is being developed, care has been taken not to lose its mechanical performance. The composites used in this study were produced using extruder and injection molding methods. Structural, morphological, elemental, spectroscopic, thermal, mechanical and flame retardant properties were determined by X-ray diffraction (XRD), scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS), FT-IR, differential thermal analysis-thermogravimetry (DTA-TG), tensile test, needle flame test (UL 94) and limiting oxygen index (LOI) tests. As a result of the thesis, flame retardant property has been successfully achieved for polypropylene. Polymer nanocomposites produced using halogen free flame retardant nanoparticles have been successfully applied in battery components used in the automotive industry as industrial applications.
