| Abstract: |
| Antibacterial activity of imidazolium based molecules bearing alkyl chains have been attracted more attentions because of their efficiency in killing bacteria. Therefore, in the present work we synthesized a polymeric macroporous structures with nanometric void size was first synthesized through high internal phase emulsion polymerization and then characterized. The FE-SEM micrographs showed that the prepared porous structure based on poly(styrene-vinyl benzyl chloride) had a uniform morphology and interconnected structure with potential ability for gas or fluid transmission. The structure, namely inner surface of pores, was then modified with imidazolium based antibacterial agents with alkyl groups in different length (C2, C4, C6, C8, C12). The antibacterial tests (measuring inhibition zone) showed that when alkyl chain was increased, the antibacterial activity of porous materials was increased. So that, the alkyl chains with more than two carbons, namely butyl, hexyl, octyl and dodecyl had more efficiency to kill the negative gram and positive gram bacteria. |
