PREPARATION AND CRYSTALLIZATION BEHAVIOR OF MULTIWALLED CARBON NANOTUBES AND POLYAMIDE 66 COMPOSITE BY SOLUTION MIXING PROCESS

摘要

Polyamide 66 (PA66), as an engineering plastics, has the advantages of high strength, excellent corrosion resistance, suitable wear resistance and easy processing property. However, it also has some defects, such as low impact strength at low temperature, low thermal stability and high water absorption. So the application of PA66 is limited, and using reinforcing fillers for polymers to modify PA66 has received considerable attention.
