Sažetak
In this paper, influence of mechanical recycling on the properties of a single-use face masks was examined. Single-use face masks were mechanically recycled by using a laboratory single-screw extruder. FTIR, TG and DSC were used to determine the structure and thermal properties of each layer of the single-use face mask, single-use face mask before and after recycling. FTIR analysis confirmed that polypropylene is the main polymer that composes each layer of the single-use face mask. The influence of recycling of a single-use face mask on its thermal properties was investigated by differential scanning calorimetry and non-isothermal thermogravimetric analysis. It was found by non-isothermal thermogravimetry that recycling does not affect thermal stability of single-use face masks. By using differential scanning calorimetry, it was determined that recycling affects the crystallinity of single-use face masks.
