Abstract: Hectorite/LiCl/nylon 6(PA6) composites were prepared through melting extrusion process, the effects of mass fraction of hectorite on structure and properties of LiCl/PA6 composites were studied. The effect of complexation reaction on the dispersion of hectorite in the matrix was also discussed. DSC and XRD research indicate that addition of hectorite is advantageous to the crystal of composites, but the crystallinity is less than that of LiCl/PA6 composites. When the mass fraction of hectorite is 5%, the crystallinity of hectorite/LiCl/PA6 composites is the largest. Meanwhile, the tensile strength and bending strength of the composites reach the maximum values of 99.17 MPa and 154.17 MPa, respectively. TEM shows that when the mass fraction of hectorite is 5%, the dispersion of hectorite in the matrix was mainly intercalated dispersion and partly exfoliated morphology. In addition, dynamic Han curves show that the viscous response dominates in hectorite/LiCl/PA6 composites. As the agglomeration of hectorite and different relaxation state of different phases for inorganic clay and organic phase, Cole-Cole curves display a phenomenon of severe smearing when the mass fraction of hectorite is greater than 5%. Hectorite/LiCl/PA6 composites not only keep the characteristics of the low melting point and show excellent mechanical properties. Hence, hectorite shows obvious enhancement effect.
