Solution blending method

PEN/carbon nanotubes hybrid films can be prepared by a solution blending method [52]. The dispersion of... 

The solution-blending method was also employed by Srivastava et al. to prepare EPDM/ EVA/organoclay ternary nanocomposites [67,68]. EVA, with 45 wt% vinyl acetate (VA), and EPDM were blended in a 50/50wt/wt ratio with 2-8 wt% H3(Ci6)i organoclay in hot toluene... 

Polymer blends were prepared by solution blending method. ... 

Although solution blending method consists in the most efificient nanoparticles dispersion technique in the polymeric matrix, it is mostly not compatible with current large-scale industrial processes. 

For the solution-blending method, the driving force for the polymer chains intercalation into the clay from solution is the entropy gained by desorption of solvent molecules, which compensates for the decreased entropy of the confined, intercalated chains [45]. Thus, intercalation using this method may only occur for certain polymer/solvent pairs. For example, polystyrene can be used with various solvents, so it is easy to choose a solvent compatible simultaneously with the clay and the polymer [46,47], whereas the polyamides may require acidic solvents, which could react with some organic heatments. 

Methylsilicone nanocomposites have been prepared by solution blending methods using three different types of hydroxyl-containing POSS (TriSilanolphenyl-POSS, TriSilanolIsobutyl-POSS and MonoSilanolIsobutyl-POSS) and one non-hydroxyl-containing POSS (Methacryl-POSS). It is noted that aggregation tendency is more pronounced... 

Very few papers have been published on the preparation of polymer blend nanocomposite from organoclays and poly(ethylene oxide)/poly(methyl methacrylate) (PEO/PMMA) blend by the solution blending method." In this section, we discuss how the blending sequence affects the microstructure of the ternary hybrid nanocomposites and especially the dispersion states of the organoclays in the polymer matrix.
