Rheology of polymer layered silicate nanocomposites

Clay nanocomposites based on poly(vinylidene fluoride-co-hexafluoropropylene): Structure and properties

“…In contrast, profound deviations of the ideal melt behavior, mainly in the low frequency limit, can be observed for the organoclay based nanocomposites. This behavior is typical for several classes of hybrid materials and has been attributed to the formation of a physically cross-linked superstructure due to the presence of the nanofillers [43][44][45][46][47]. Essentially, the development of such a physical network tends to increase the relaxation time of the melt, while at high frequencies the viscoelastic spectra of nanocomposites exhibit reduced sensitivity to the presence of nanofillers.…”

Polymer nanocomposites

“…Crucial to these studies is the wide array of synthetic chemistry tools for nanoparticle preparation along with polymerization methods such as grafting-to and graftingfrom that have been developed and practiced over the last two decades. The synthetic issues, 4,5 colloidal particle physics and processing 10,11 as applied to PNCs, while quite mature, have many outstanding issues and these have been recently articulated in substantial detail. 1,3,6,10,[12][13][14] This article will concentrate on the polymer physics aspects of this complex subject.…”

Morphological study of magnesium hydroxide nanoparticles precipitated in dilute aqueous solution

“…Many studies have been recently focusing on the development and characterization of new nanocomposites exhibiting anisotropic morphologies [8][9][10][11][12][13][14]. Specific mechanical and physical properties are expected when the filler particles are plateletshaped [15,16]. The advantage of composites containing nanoplatelets is mainly the improvement of their mechanical reinforcement properties as well as ''barrier properties'' that are supposed to play a significant role in fire resistance, for lower filler loading than traditional composites [14].…”
