Conductive polypyrrole/UV cured acrylate nanocomposite coatings were prepared via a facile approach called simultaneous photopolymerization. In our previous study, the mechanisms of the polymerizations of pyrrole and acrylate in this process were discussed. In the current work, the mechanical and conductive properties were investigated by correlating them with the structural and compositional changes observed in the coating systems. Various percentages of pyrrole and acrylate monomers along with their corresponding UV activators, AgNO₃ and DAROCUR 1173 respectively, were used to prepare the polypyrrole/UV cured acrylate composite coatings. The percentage of the mixture of pyrrole and AgNO₃ in the formulation varied from 25 % to 60 %. Scanning electron microscopy (SEM) results indicated that the deposition of polypyrrole/Ag composite particles occur closer to the substrate. Based on the conductive atomic force microscopy (AFM) results, all the coatings in this study exhibited higher current densities on the bottom side of the coatings and the only coatings prepared with the formulations containing 45 % or higher of pyrrole and AgNO₃ mixture exhibited conductivity on top side of the coatings. From the thermogravimetric analysis (TGA) results, it can be inferred that the increase in percentage of polypyrrole/Ag in the coating results in changes in the chemical structure of the UV cured acrylate binder. Dynamic mechanical analysis (DMA)results suggested that the incorporation of polypyrrole/Ag composite during the photopolymerization process leads to plasticization of polymer network causing an increase in dissipative-like behavior in the coatings.

导电聚吡咯/紫外光固化丙烯酸酯纳米复合涂料是通过一种称为同时光聚合的简便方法制备的。在我们以前的研究中，讨论了吡咯和丙烯酸酯在该过程中的聚合机理。在当前的工作中，通过将机械性能和导电性能与涂料体系中观察到的结构和成分变化相关联，对机械性能和导电性能进行了研究。分别使用不同百分比的吡咯和丙烯酸酯单体及其相应的紫外线活化剂AgNO ₃和DAROCUR 1173，来制备聚吡咯/紫外线固化的丙烯酸酯复合涂料。吡咯和AgNO ₃的混合百分比在配方中的含量从25％变化到60％。扫描电子显微镜（SEM）结果表明，聚吡咯/ Ag复合颗粒的沉积更靠近基材。根据导电原子力显微镜（AFM）结果，本研究中的所有涂层在涂层的底部均表现出较高的电流密度，并且只有用含有45％或更高的吡咯和AgNO ₃的配方制备的涂层该混合物在涂层的顶面上显示出导电性。从热重分析（TGA）结果可以推断，涂层中聚吡咯/ Ag百分比的增加会导致UV固化丙烯酸酯粘合剂的化学结构发生变化。动态力学分析（DMA）结果表明，在光聚合过程中聚吡咯/银复合物的引入导致聚合物网络的增塑，从而导致涂层中类似耗散性的行为增加。
