Poli(dietilamino etil metakrilat-ko-etil metakrilat)/poliindol kompozitlerin sentezi ve karakterizasyonu

In the current study; In the first stage, amphiphilic poly(DEAEMA-co-EMA) copolymers were synthesized from the hydrophilic monomer 2-diethylamino ethylmethacrylate (DEAEMA) and the hydrophobic monomer ethyl methacrylate (EMA) using free radical polymerization. In the second stage, five series composites were prepared at different concentrations using indole conductive monomer in the presence of iron(III) chloride (FeCl3) using the in situ oxidative polymerization technique in poly(DEAEMA-co-EMA) copolymer. The structures of the polymer composites (PCs) were elucidated using FTIR, TGA, SEM, AFM characterization techniques. PCs exhibited significant performance on bacterial biofilm adhesion tested using the Streptococcus mutans by the test tube method (TM). In this study, the 0.006 mg/ml concentration of PC1 reduced the biofilm formation of Streptococcus mutans by 83.199%. As the concentration and amounth of poly(indole) in the PCs increases, the % antibiofilm effect also increases. Antibacterial activity of the prepared poly(DEAEMA-co-EMA)/PIN composites Escherichia coli and Staphylococcus aureus evaluated against and the results showed that the composite had antibacterial activity. Moreover, Antioxidant studies of composites was carried out. The results showed that the enhanced bioactivity of poly(DEAEMA-co-EMA)/PIN(90%) composite. Further, the antioxidant studies findings indicated that PIN exhibited the highest viability value throughout all the other samples. Also, dielectric properties of composite this films were evaluated depending on frequency based on the values of dielectric loss and tangent.
