聚酰胺改性研究进展

Research progress on the modification of polyamide

作为开发最早的一种工程材料,聚酰胺具有强度大、韧性高、耐热性好等优势而广泛应用于航空、电子、器械等领域。综述了近年来聚酰胺的共聚改性、共混改性、纤维增强、无机纳米粒子填充等改性方法,指出共混改性是聚酰胺改性的研究重点,并对未来聚酰胺的研究方向进行了展望。

As one of the earliest developed engineering materials,polyamides are widely used in aeronautics,electronics,equipment and other fields due to their advantages such as high strength,high toughness,and good heat resistance.The modification methods of polyamide such as copolymerization modification,blending modification,fiber reinforcement and inorganic nanoparticle filling developed in recent years were reviewed. It was pointed out that the way of blending modification became the focus of research. In the future,the research of polyamides will develop in the direction of high strength,high performance,and functionalization.
