Description

technical field [0001] The invention relates to the field of polymer materials, in particular to a nano polyamide composition with metallic luster and a preparation method thereof. Background technique [0002] Polyamides (PA for short) have excellent comprehensive properties and can be used directly. At the same time, fillers can also be added to improve the strength, rigidity and dimensional stability of composite materials to meet the use requirements of some special requirements. Among many reinforcing materials, nanomaterials can be used as an ideal choice, with the characteristics of small addition amount and obvious effect. Nanomaterials refer to materials that have at least one dimension in a three-dimensional space that is in nanometer size (within 100nm) or consists of them as basic units. Nanomaterials have a unique small size effect and large surface energy. Only a small amount of nanomaterials can be added to give composite materials excellent mechanical proper...
