Abstract
After the pandemic, we became more aware of microorganisms around us and realized how these creatures could affect our health and environment. In this regard, this project was planned to prepare polymer-based nanocomposites with antibacterial properties. This study selected a cationic polymer, poly (diallyl dimethylammonium) chloride (PDDA), along with graphene oxide reinforcement to achieve this goal. The mechanical and thermal properties of PDDA, GO, and the prepared PDDA-GO nanocomposite will be characterized by dynamic mechanical analysis (DMA) and differential scanning calorimetry (DSC). A high glass transition (Tg) (around 250 .C) has been identified with DSC and DMA for the PDDA. The minimum inhibitory concentration (MIC) technique was used to study their antimicrobial activities against Staphylococcus aureus and Escherichia coli. The early results for the PDDA were shown to be moderately effective against E. coli and S. aureus, with values of 64 and 16 ƒÊg/mL, respectively.
