Antibacterial Ability of HPQM base Neusilin/Natural Rubber Reinforced with Carbon Black

This work studied antibacterial ability of natural rubber (NR) reinforced carbon black N330 at loadings 0, 20, 40 and 60 parts per hundred rubber (phr) and 2-Hydroxypropyl-3-Piperazinyl-Quinoline carboxylic acid Methacrylate (HPQM) based Neusilin at loadings 0, 3 and 5 phr were used against Escherichia coli (E.coli) ATCC 25923 and Staphylococcus aureus (S.aureus) ATCC 25922. The Inhibition zone (Disk diffusion) and Plate Count Agar (PCA) methods were employed to assess the ability of the anti-bacterial performance, cure characteristics and mechanical properties such as tensile modulus, tensile strength, elongation at break and hardness. The results suggested that increasing HPQM in appearance of inhibition zone and 99.9 percent reduction of E.coli. The antibacterial ability HPQM base Neusilin at loadings 5 phr and carbon black at loadings 20 phr were better. The antibacterial ability of NR vulcanizates depends on the level of reinforcement. The tensile strength with using 40 phr of carbon black loading was suggested in this work.
