TLDR
In this paper, the preparation of nanocomposites by the usage of ultrasound was focused on synthesizing polystyrene/alumina composites using commercial alumina nanoparticles of approximately 200 nm size.Abstract:
Polymer nanocomposites offer remarkable enhancement in properties compared to pristine polymers, and also compared to conventional micro- and macro-composites. The present study is focused on the preparation of nanocomposites by the usage of ultrasound. Polystyrene/alumina nanocomposites were synthesized using commercial alumina nanoparticles of approximately 200 nm size. These particles were dispersed in polystyrene solution by subjecting to ultrasound. Composites were synthesized at different filler loadings varying from 0.2% to 1% by weight. Dispersion characterization of these composites was carried out using scanning electron microscopy and X-ray diffraction. X-ray diffraction data revealed the incorporation of the filler into the polymer matrix. The mechanical properties, mainly tensile and impact properties, of the composites were studied to analyse the effect of nanofillers on the enhancement in functional properties compared to the neat polymer. Tensile strength and modulus varied with the filler...read more

Acoustically-enhanced particle dispersion in polystyrene/alumina nanocomposites
TL;DR: In this article, the effect of frequency on filler dispersion in the polymer matrix was studied by SEM analysis and functional property enhancement of the composite material was found to be better at low filler loadings as compared with neat polymer and also with composites prepared without ultrasound.

Average stress in matrix and average elastic energy of materials with misfitting inclusions
Trevor A. Mori,K Tanaka +1 more
TL;DR: In this paper, a method of calculating the average internal stress in the matrix of a material containing inclusions with transformation strain is presented. But the authors do not consider the effects of the interaction among the inclusions and of the presence of the free boundary.

Polymer-layered silicate nanocomposites: preparation, properties and uses of a new class of materials
TL;DR: In this article, a review of polymer-layered silicate nanocomposites is presented, where the polymer chains are sandwiched in between silicate layers and exfoliated layers are more or less uniformly dispersed in the polymer matrix.

Polymer Layered Silicate Nanocomposites
TL;DR: In this paper, a new, versatile and environmentally benign synthesis approach by polymer melt intercalation is discussed. But, unlike in-situ polymerization and solution inter-calation, melt interalation involves mixing the layered silicates with the polymer and heating the mixture above the softening point of the polymer.

TL;DR: In this paper, the carboxyl and amino end groups were attributed to ammonium cations (-NH3+) of nylon molecules, because the difference agreed with the anion site concentration of the montmorillonite in NCH.
