Poly(N-methylpyrrole) (PNMPy) and Poly(Pyrrole/N-methylpyrrole) P(Py/NMPy) copolymer were prepared in an aqueous solution by interfacial polymerization in the presence of surfactive dopant dodecylbenzene sulphonic acid (DBSA). Structural, thermal, morphological and dielectric characterization studies were performed by Fourier transform infrared (FT-IR), X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), Fluorescence (FL), Thermogravimetric (TG), Scanning electron microscopy (SEM-EDS), Atomic Force Microscope (AFM), Brunauer-Emmett-Teller (BET) surface area and LCR meter analyses. The antimicrobial activity of the samples was investigated by the Agar diffusion method. Characterization studies showed that both PNMPy and P(Py/NMPy) were semi-crystalline in nature, depending on the arrangement of methyl groups in the polymer chains and/or the DBSA doping. Also, due to the interaction between DBSA and polymer chains, the samples showed a significant FL emission intensity. In the surface analyses, phases of polymer matrix and DBSA were clearly observed. Dielectric analyses showed that the charge transport mechanisms of both samples are highly compatible with the correlated barrier hopping (CBH) model. The activation energies required for the hopping of the charge carriers in the PNMPy and P(Py/NMPy) chains were calculated as 0.23 and 0.17 eV, respectively. In antibacterial tests against the various bacteria species, PNMPy formed an inhibition zone between 26 and 29 mm, while the copolymer formed an inhibition zone between 29 and 32 mm. The results showed that P(Py/NMPy) copolymer is a multifunctional material that is very suitable for electronic and photoelectric applications, as well as biomedical ones relating to antibacterial agents, infection-resistant medical devices and florescent antibiotic probe.

聚(N-甲基吡咯) (PNMPy) 和聚(吡咯/N-甲基吡咯) P(Py/NMPy) 共聚物在表面活性掺杂剂十二烷基苯磺酸(DBSA) 存在下通过界面聚合在水溶液中制备。通过傅里叶变换红外 (FT-IR)、X 射线衍射 (XRD)、X 射线光电子能谱 (XPS)、荧光 (FL)、热重 (TG)、扫描电子进行结构、热、形态和介电表征研究显微镜 (SEM-EDS)、原子力显微镜 (AFM)、Brunauer-Emmett-Teller (BET) 表面积和 LCR 仪表分析。通过琼脂扩散法研究样品的抗菌活性。表征研究表明，PNMPy 和 P(Py/NMPy) 本质上都是半结晶的，取决于聚合物链中甲基的排列和/或 DBSA 掺杂。此外，由于 DBSA 和聚合物链之间的相互作用，样品显示出显着的 FL 发射强度。在表面分析中，可以清楚地观察到聚合物基质和 DBSA 的相。介电分析表明，两种样品的电荷传输机制与相关势垒跳跃（CBH）模型高度兼容。PNMPy 和 P(Py/NMPy) 链中电荷载流子跳跃所需的活化能分别计算为 0.23 和 0.17 eV。在针对各种细菌的抗菌试验中，PNMPy 形成了 26 至 29 mm 的抑菌圈，而共聚物形成了 29 至 32 mm 的抑菌圈。
