采用同步法制备了聚苯胺（PANI）/聚（2-丙烯酰胺基-2-甲基丙磺酸）（PAMPS）半互穿网络聚合物（semi-IPNs）。利用傅里叶变换红外光谱、X射线衍射、固态13C-NMR、差示扫描量热法（DSC）和热重分析（TGA）研究了互穿PANI/PAMPS半互穿网络的形成和性能。还研究了 PAMPS 与 PANI 作为聚合酸掺杂剂的相互作用。与纯聚苯胺相比，这些半互穿网络具有不同的微观结构。每个半互穿网络都排列了堆积结构和几个分解步骤，而纯聚苯胺则表现出单个非晶峰和一个分解步骤。核磁共振谱显示这些峰在半互穿网络中变宽并向低场移动。使用 DSC 和 TGA 观察到 PANI 和 PAMPS 之间的热反应，两种技术的数据一致。
Polyaniline (PANI)/poly(2‐acrylamido‐2‐methylpropane sulfonic acid) (PAMPS) semi‐interpenetrating network polymers (semi‐IPNs) were prepared using the simultaneous method. The formation and properties of the interpenetrating PANI/PAMPS semi‐IPNs were investigated using Fourier transform infrared spectroscopy, X‐ray diffraction, solid‐state 13C‐NMR, differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA). The interaction of PAMPS with PANI as a polymeric acid dopant was also investigated. These semi‐IPNs had a different microstructure compared to that of pure PANI. Packing structures and several decomposition steps were ordered for each semi‐IPN, while pure PANI exhibits a single amorphous peak and one decomposition step. The NMR spectra show that these peaks broaden and shifted downfield in the semi‐IPNs. A thermal reaction between PANI and PAMPS was observed using DSC and TGA, and the data from the two techniques are in agreement.
