제목 Effect of layered silicates on the crystallinity and morphology of HDPE/ MMT nanocomposites
초록 Generally, it has been known that melt intercalation process is the most effective process for cost reduction compared to other methods in preparing polymer/layered silicate nanocomposites.
HDPE-g-MAH/MMT master batch and HDPE/MMT nanocomposites were prepared by melt mixing using a twin screw extruder. The master batch was first prepared with HDPE-g-MAH and MMT in order to enhance the dispersion of MMT. HDPE/MMT nanocomposites were prepared with the mixing of HDPE and MMT or master batch.
The structures and morphologies of the nanocomposites were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM) and scanning electron microscopy (SEM). The crystallization behavior and crystal forms in the HDPE and HDPE/MMT nanocomposites blown films were evaluated using X-ray diffraction (XRD) and differential scanning calorimetry (DSC).
The crystallinity and morphological characteristics of HDPE/MMT nanocomposites were affected by the MMT content and the degree of exfoliation of MMT.
