Description

technical field [0001] The invention relates to the field of materials, in particular to a conductive polyphenylene ether / polyamide 66 composition and a preparation method thereof. Background technique [0002] Polyphenylene oxide (PPO) has good mechanical properties, heat resistance and chemical stability, and can be used continuously in the temperature range of -160 to 190 ° C. It is the material with the best creep resistance among thermoplastic engineering plastics. Polyamide 66 (PA66) is a crystalline resin with excellent chemical resistance and processability, but its high water absorption leads to a decrease in its mechanical properties and poor dimensional stability. In order to improve the processability and solvent resistance of PPO, polyphenylene ether and polyamide 66 can be blended to prepare PPO / PA66 composition. However, due to the thermodynamic incompatibility of amorphous PPO and crystalline PA66, the blend dispersed phase domain size is too large, the phas...
