Herein, we have reported that the polyaniline (PANI), as a polymeric catalyst, exhibits an outstanding efficiency for the curing of phthalonitrile resin as verified by differential scanning calorimetry (DSC) with a high enthalpy, in which the triazine structure is the dominating curing products as confirmed in the Fourier transform infrared (FTIR) spectra. Thermogravimetric analysis (TGA) and nanoindentation tests have been carried out to investigate the thermal and mechanical properties of the cured PANI/phthalonitrile resin. The results demonstrate that the PANI/phthalonitrile resin not only manifests a high char yield up to 24.7% at temperature of 850 °C in the air atmosphere, but also possesses an improved hardness that is 81.8% higher than that of regular small molecule of amine catalyst/phthalonitrile resin.

本文中，我们已经报道了聚苯胺（PANI）作为聚合催化剂，具有高焓的差示扫描量热法（DSC）证明了对苯二腈树脂的固化具有出色的效率，其中三嗪结构是主要的固化傅里叶变换红外（FTIR）光谱中确认的产品。已经进行了热重分析（TGA）和纳米压痕测试，以研究固化的PANI /邻苯二甲腈树脂的热和机械性能。结果表明，PANI /邻苯二甲腈树脂不仅在空气中在850°C的温度下具有高达24.7％的高炭收率，而且具有比常规小分子胺高81.8％的硬度。催化剂/邻苯二甲腈树脂。
