Microstructure and Mechanical Properties of Nanoperlite/LDPE Nanocomposites: The Effects of Nanoperlite Loading

Nanoperlite/LDPE nanocomposites were prepared via film blowing method and the effect of various nanoparticles loading on the microstructure and mechanical properties of the nanocomposites were investigated. The morphology and dispersion state of nanoperlite was evaluated using a Scanning electron microscopy (SEM) analysis. Mechanical properties of the nanocomposites containing various nanoperlite loadings were investigated using a tensile testing machine. The results of SEM photomicrographs show a good dispersion of nanoparticles during the sample preparation process. The modulus of the prepared nanoperlite/LDPE nanocomposites show an increase up to 75% with the rise of the nanoparticle loadings. The other properties such as falling dart impact strength and tea resistance were improved by the introduction of various loadings of nanoperlite into the LDPE matrix. Nanoperlite/LDPE nanocomposite films were prepared with the enhanced physical and mechanical properties due to the good dispersion of nanoparticles into the polymer matrix
