Investigating a Novel EVA/POE/LDPE Foam Compound with Nano ZnOfor Antibacterial Yoga Mat Applications

This study investigates the potential of a novel foam compound composed of ethylene vinyl acetate(EVA), polyolefin elastomer (POE), and low-density polyethylene (LDPE) for yoga mat applications.The main focus is on promoting cleanliness and us er safety during yoga. The study investigates effectof Nano zinc oxide (Nano ZnO) content on the overall performa n ce of foam. Nano ZnO particleswere added in different a m ounts (۱ wt%, ۲ wt%, ۳ wt%, ۴ w t%, and ۵ wt%) to create long-lastingantibacterial properties. Tests on ten sile strength, elongation at break, hardn ess, and rebound weredoes to assess t he mechanical aspects of samples. Results shown that using ۲ wt% nano ZnO ach ievesa good balance between mechanical strengt h and antibacterial capability. Increasing nano ZnOcontent improves antibacter ial effects ag ainst common yoga studio bacterias like Escherichia coli(E.coli) (negative gram) and Staphylococcus aureus (S.aure us) (positive gram), but it reducedmechanical strength once it went over ۲ wt%. The antibacterial efficacy of the foam compound wasevaluated using the Microbiological solid diffusion assay.
