| Abstract: | Layered materials (MMT,LDH) were successfully modified by chain end functionalized polyethylene via an ion exchange method.The samples were characterized by using elemental analysis,Fourier transform infrared (FTIR) spectrum,X-ray diffraction (XRD),scanning electron microscopy (SEM),transmission electron microscopy (TEM) and thermogravimetric analysis (TGA).The XRD results demonstrated that MMT was successfully exfoliated with the disappearance of 001] peak.For the LDH,the peak 003] moved to a low angle and greatly weakened,indicating that LDH was successfully functionalized and completely intercalated or exfoliated.HDPE/layered nanocomposites were obtained between HDPE and different content of functional layered materials.The SEM and TEM results of nanocomposites showed the layered materials were well dispersed in the HDPE matrix,with a particle size of 100-200 nm. |
