Abstract
The dispersion of nanofillers in in polymer matrix is a critical issue not only because of its scientific importance but also for technical reasons. Quantitative analysis of extent of dispersion of fillers by measuring the rheological characteristics of thermoplastic polymer nanocomposites has great technical importance for improving processing conditions, for understanding the fundamental characteristics of the materials at the nanoscale and structureproperties relationships of nanocomposites materials and in their commercial applications. Viscoelastic properties including the percolation threshold are extremely sensitive to how the nanofillers are dispersed. The percolation threshold, corresponding to the onset of solid-like behaviour can be observed at lower filler concentrations as the dispersion is improved, or the interaction between the nanofiller and the matrix is stronger or the filler aspect ratio is larger. This review highlights the various factors such as nature of filler, dispersion of fillers, fabrication techniques for polymer nanocomposites, interaction between filler and polymer, filler-filler interactions and temperature which affect the rheological percolation of thermoplastic polymer nanocomposites.
