A method for preparing and applying a carbon fiber phthalocyanine sizing agent is disclosed. The method involves synthesizing a liquid phthalocyanine monomer containing siloxane segments through hydrosilylation and nucleophilic addition reactions, and then formulating it into a dilute solution-type sizing agent. Compared with existing technologies, this invention overcomes the limitation of traditional sizing agents relying primarily on physical compatibility with the resin matrix. Through an integrated "structure-function" design, the sizing agent simultaneously performs the dual functions of interface modification and resin co-curing. This sizing agent can form an active interface layer on the carbon fiber surface, co-curing with the phthalocyanine resin to form a chemically bonded network, increasing the interlaminar shear strength of the composite material by more than 30% and achieving a temperature resistance of up to 400℃, making it suitable for manufacturing high-temperature components for aerospace applications. The presence of a multidimensional conductive network on the carbon fiber surface endows the composite carbon fiber material with excellent electromagnetic shielding properties, and also improves the strength, toughness, and wear resistance of the carbon fiber.
