Abstract
A novel hybrid substance, ZnO: MWCNT, are fabricated from prepared pellets using a pulsed laser ablation liquid technique at varied MWCNT concentrations (0, 3, 5, 10, and 15) wt%. The study cast at the effect of MWCNT concentration on the structure of prepared samples using FTIR and tested for different types of antimicrobial activity. From FTIR examination, one can observe that all the prepared ZnO: MWCNT samples with different concentrations have different types of band (stretching and bending). All the prepared composite samples with various concentrations have showed influence on different types of bacterial, however in general the annealing ZnO, MWCNT and the composite nanomaterial with 15%MWCNT have higher zone of antibacterial activity for studying types of bacterial inhibition.
