Journal ArticleDOI
Current issues in research on structure–property relationships in polymer nanocomposites
Josef Jancar,Jack F. Douglas,Francis W. Starr,Sanat K. Kumar,Philippe Cassagnau,Alan J. Lesser,S. S. Sternstein,Markus J. Buehler +7 more
TL;DR: In this paper, the state of the art regarding the understanding and prediction of the macro-scale properties of polymers reinforced with nanometer-sized solid inclusions over a wide temperature range is established.
Journal ArticleDOI
Intercalated clay nanocomposites: Morphology, mechanics, and fracture behavior
Adam S. Zerda,Alan J. Lesser +1 more
TL;DR: In this paper, intercalated nanocomposites of modified montmorillonite clays in a glassy epoxy were prepared by crosslinking with commercially available aliphatic diamine curing agents.
Journal ArticleDOI
The effect of network architecture on the thermal and mechanical behavior of epoxy resins
TL;DR: In this article, the effects of crosslink functionality, molecular weight between crosslinks (Mc), and chain stiffness display on the thermal and mechanical behavior of epoxy networks are determined and the fracture behavior is the result of the fracture toughness being controlled by the ability of the network to yield in front of the crack tip.
Journal ArticleDOI
Compressive behavior of microcellular polystyrene foams processed in supercritical carbon dioxide
TL;DR: In this paper, the authors used an anisotropic foam model to predict the effect of cell size and shape on the compressive yield stress of microcellular polystyrene foams.
Journal ArticleDOI
Highly concentrated, intercalated silicate nanocomposites: Synthesis and characterization
TL;DR: In this paper, a model for estimating the transition concentration of the intercalated morphology of a PMMA-layered silicate nanocomposite is presented. But the model assumes that the composite volume is saturated with inorganic material, and the d spacing decreases to homogeneously distribute the polymer volume.
