Description

technical field [0001] The invention relates to the technical field of composite materials, in particular to a carbon nanotube reinforced cyanocarbon nanotube composite polyarylether nitrile composite material and a preparation method thereof. Background technique [0002] Polyarylene ether nitrile is a kind of semi-crystalline polymer with excellent comprehensive performance, which has the advantages of high mechanical strength, flame retardancy, heat resistance and creep resistance, etc. It is expected to be used in the automotive industry, electronic appliances and aerospace play an important role in other fields. The main problem that has limited the application of PEN in special functional materials for a long time is the synthesis cost and processing fluidity of polymer PEN. Through years of research, our research group has mastered the low-cost synthesis technology of PEN, developed a series of PEN polymers to meet different needs, and developed the prepolymer phthal...

AI Technical Summary

Problems solved by technology

Introducing a small amount of carbon nanotubes into the polymer matrix can endow the material with excellent mechanical properties and barrier properties, good thermal properties and dimensional stability, unique flame retardancy and special optical properties, so polymer / carbon Nanotube composites have attracted extensive attention from material researchers and have become a hot spot in material research at present and even in the future. However, due to the van der Waals force, carbon nanotubes are usually easy to agglomerate, so it is difficult for pure carbon nanotubes to be composited in polymers. dispersed in the material
