Durability of LDPE Nanocomposites with Clay, Silica, and Zinc Oxide—Part I: Mechanical Properties of the Nanocomposite Materials

Abstract EN

Three types of LDPE-based nanocomposites with montmorillonite clay, silica, and zinc oxide were prepared by melt blending the nanofiller with the resin.

As a prelude to studying their durability, the extent of reinforcement of the LDPE matrix by the nanofillers was investigated using mechanical, thermal, and microscopic studies of the composites.

No significant chemical modification of the polyethylene matrix was observed as a result of the processing of the composite compound.

While reinforcement was obtained in all cases, the efficiency of reinforcement appears to be qualitatively influenced by surface functionalization, filler interactions, and the extent of dispersion of the filler in the matrix as well as the specific surface area of the nanoparticle fillers.
