摘要

石墨烯具备独特的结构和优异的性质，仅添加少量的石墨烯就能使聚合物的性能得到大幅度的提高。本文采用X射线衍射法（XRD）和差示扫描量热法（DSC）研究了尼龙6（PA6）和尼龙6／氨基化石墨烯（PA6/AG）复合材料的晶型和非等温结晶行为。结果表明，氨基化石墨烯（AG）加入前后，PA6的晶型没有发生明显转变，且Avrami方程可以很好地描述PA6和PA6/AG的非等温结晶行为，氨基化石墨烯在尼龙6结晶过程中起着异相成核作用，提高了PA6的结晶温度和结晶速率。

Abstract

Graphene has a unique structure and excellent properties. The performance of the polymer can be greatly improved by adding only a small amount of graphene. The crystallographic forms and non-isothermal crystallization kinetics of polyamide 6(PA6)and polyamide 6/Amino graphene(PA6/AG) composite were investigated by X-ray diffraction(XRD)and differential scanning calorimetry(DSC).The results show that

the addition of AG couldn't lead to a distinct change to crystallographic form of PA6.The Avrami equation could successfully discribe the isothermal cryatallization behavior of PA6 and PA6/AG composite.AG in PA6/AG composite could serve as effective heterogeneous nucleating agent

which made the crystallization temperature increased and crystallization rate accelerated.
