| titleOfInvention | Functionalized aramid superfine fiber and preparation method and application thereof |
| abstract | The invention discloses a functionalized aramid superfine fiber and a preparation method and application thereof.A polyfunctional group polymer with sulfonic acid, phosphoric acid, carboxylic acid, hydroxyl, phenolic hydroxyl and pyridyl is used as a dispersing agent, and aromatic diacid chloride and aromatic diamine are subjected to low-temperature solution polymerization in an organic solvent containing an acid absorbent to obtain the aramid superfine fiber which is easy to disperse and has active functional groups on the surface; and mixing the functionalized aramid superfine fiber with epoxy resin and a curing agent, and curing to obtain the high-performance thermosetting nano composite material. The method can synthesize the aramid fiber superfine fiber in a large scale, the fiber diameter can be effectively controlled to be below 100 nanometers, the obtained aramid fiber superfine fiber is easy to disperse in thermosetting or thermoplastic polymers, the interface action is strong, and the strength and the toughness of the material can be greatly improved. |
