A high performance copolymer was prepared by using epoxy (EP) resin as matrix and 3,10,17,24‐tetra‐aminoethoxy lead phthalocyanine (APbPc) as additive with dicyandiamide as curing agent. Fourier‐transform infrared spectroscopy, dynamic mechanical analysis (DMA), differential scanning calorimetric analysis (DSC), and thermogravimetric analysis (TGA) were used to study the curing behavior, curing kinetics, dynamic mechanical properties, impact and tensile strength, and thermal stability of EP/APbPc blends. The experimental results show that APbPc, as a synergistic curing agent, can effectively reduce the curing temperature of epoxy resin. The curing kinetics of the copolymer was investigated by non‐isothermal DSC to determine kinetic data and measurement of the activation energy. DMA, impact, and tensile strength tests proved that phthalocyanine can significantly improve the toughness and stiffness of epoxy resin. Highest values were seen on the 20 wt% loading of APbPc in the copolymers, energy storage modulus, and impact strength increased respectively 388.46 MPa and 3.6 kJ/m2, T g decreased 19.46°C. TGA curves indicated that the cured copolymers also exhibit excellent thermal properties.

环氧树脂-共胺-官能化酞菁铅的固化行为，热学和力学性能的研究
以环氧（EP）树脂为基质，以3,10,17,24-四氨基乙氧基铅酞菁（APbPc）为添加剂，以双氰胺为固化剂制备了高性能共聚物。使用傅里叶变换红外光谱，动态力学分析（DMA），差示扫描量热分析（DSC）和热重分析（TGA）来研究固化行为，固化动力学，动态力学性能，冲击和拉伸强度以及热稳定性EP / APbPc共混物。实验结果表明，APbPc作为一种协同固化剂，可以有效降低环氧树脂的固化温度。通过非等温DSC研究共聚物的固化动力学，以确定动力学数据并测量活化能。DMA，影响，拉伸强度试验证明，酞菁可以显着提高环氧树脂的韧性和刚度。共聚物中APbPc的20 wt％含量最高，储能模量和冲击强度分别提高了388.46 MPa和3.6 kJ / m如图2所示，T g降低19.46℃。TGA曲线表明，固化的共聚物还表现出优异的热性能。
