Abstract
The invention relates to polyamine containing a triazole ring and a preparation method and application thereof. The preparation method of the polyamine comprises the following steps of: preparing an azide by a nucleophilic substitution reaction; synthesizing the polyamine containing the triazole ring by the Huisgen cycloaddition reaction of the azide and a compound with alkynyl amine; and applying the polyamine containing the triazole ring to the preparation of polyimide. The invention has the following advantages that: polytriazole imide has superior processable property and can be dissolved in polar solvents, such as DMAc, DMF, DMSO, NMP and the like; the prepared polytriazole imide has the properties of the polyimide, such as superior heat resistance, low-temperature resistance, chemical resistance, mechanical properties, dielectric and insulation properties, fire retardance, bonding properties and the like; the polytriazole imide can be used as a functional polyimide material and is especially suitable for serving as a metal coating material and a corrosion-resistant material; and the novel polytriazole imide material has extensive application prospect in the fields of aviation, spaceflight, ships, micro-electronics and the like.
