Synergy between fillers in organomontmorillonite/graphene–PLA nanocomposites

Models to Predict the Viscosity of Metal Injection Molding Feedstock Materials as Function of Their Formulation

“…In Figure 3, it can be seen that for the PP-based binder the best fit is undeniably the Grunberg-Nissan model. However, for the POM-based binder the van der Wyk model is only marginally better to the Grunberg-Nissan model (i.e., the sum of the square differences for the van der Wyk model is 0.179 (Pa¨s) 2 and for the Grunberg-Nissan model is 0.211 (Pa¨s) 2 ). It is important to mention that these two models include an interaction parameter.…”

“…Please note that mixing rules can also be extended beyond binary mixtures, but for simplicity and because of the blends investigated, binary mixing rules are shown here. In Table 1, Equations (1) and (2) are simple models that depend on the viscosity and weight fraction of each component; these models neglect interactions between the different components of the mixture. Equations (3)-(5) take the influence of interactions into account.…”

“…Ideally, mixing two constituents enhance a material's property beyond simple additivity; thereby exhibiting synergistic behavior [1]. Synergistic effects have been observed for example in nanocomposites where adding a small amount of nanoparticles leads to a substantial increase in their mechanical and barrier properties [2], as well as their thermal conductivity [3].…”

Preparation and analysis of multi-layered hybrid nanostructures

“…Graphene based polymer hybrid nanocomposites werealsoreported (Acharya et al, 2007;Das and Prusty et al, 2013;Nandi et al, 2013;Chakraborty et al, 2014;Yadav et al, 2014;Angelopoulou et al, 2015;Bouakaz et al 2015;Oran et al, 2015;Yana et al, 2016). But recently in the field of inorganic NM, layered double hydroxide (LDH) has emerged as the most powerful NMfor the preparation of multifunctional hybrids for various applications (Yuan et al, 2012).…”

“…The combination of multi-dimensional NM or layered NS were used to prepare hybrid nanostructures with many advantages due to each kind of NM or NS (Bouakaz et al, 2015;Oraon et al, 2015;Alsharaeh et al, 2016;Chen et al, 2016;; Pérez del Pino et al, 2016,Kavinkumar et al, 2016Zhao et al, 2016).These kinds of hybrid nanostructures with exceptional properties are effective and they were reported for the potential applications (Latorre-Sanchez et al, 2012;Lonkar et al, 2015).Many hybrid materialswere reported, which can bemade usingdifferent NS.But recently organic-inorganic hybrid NS haveshown considerable attention (Mishra et al, 2010;. Among the various organic NS materials, graphene oxide (GO)has a tremendous interest in a scientific research.Because GO istwo dimensional (2D) andconductinglayered NMand it consists of one atom-thick planar sheets of sp 2 -bonded honeycomb structure of carbon atoms (Low et al, 2015).GO possesses extraordinary mechanical, thermal, electronic and physical properties, (Hansora et al, 2015;Lonkar et al, 2015),more importantly it contains a range of reactiveoxygen functional groups (e.g., hydroxyl groups) .Therefore, GO wasused to prepareorganic-inorganic hybrid NS (Wu et al, 2012;Nandi et al, 2013;Esmaeili et al, 2014;Yadav et al, 2014;Angelopoulou et al, 2015, Low et al, 2015Jain et al,2016).Many scientists havepreparedhybrid NS usingdifferent metal and inorganic NM filled with GO, e.g., Titanium oxide-graphene (Heet al, 2016;Pérez del Pino et al,2016;Zhao et al,2016),Manganese-nickel mixed oxide/graphene (Latorre Sanchez et al,2015), Organomontmorillonite/graphene (Bouakaz et al 2015;Oraon et al, 2015),Calciumcarbonate/GO ,Silver nanoparticle/GO (Kavinkumaret al, 2016),Cobalt oxide nanoparticles/reduced GO(Alsharaeh et al,2016),Zinc oxide nanorods/graphene …”
