摘要
Typical montmorillonite clays (Cloisite (R) Na(+), Cloisite (R) 3013) were modified by treatment with octadecyl ammonium chloride (ODC) and successive additions of octadecylamine (ODA). XRD analyses of the modified clays indicated an increase of the basal spacing of the (00 1) planes depending on the ODC or ODA additions. Nanocomposites were prepared by dispersing the modified clays (3% w/w concentration) in LDPE, using a Brabender mixer. XRD measurements of the obtained products indicated in some cases the achievement of intercalation effects, which were confirmed by TEM analysis. Some thermal, mechanical, dynamic-mechanical and theological properties were evaluated and correlated to the degree of intercalation. (c) 2006 Elsevier Ltd. All rights reserved.
