“…PEO is also a very suitable material for hot melt extrusion due to its very good processing ability in different processing conditions, where polymer of low molecular weight can act as a plasticizer for high molecular weight polymer [24]. (PEO)/clay nanocomposites offer new promising materials which display a great potential for use in various application fields [25][26]. The hydrophilic nature and very strong polarity of PEO presents an important advantage when preparing intercalates of PEO and hydrophilic silicate clay platelets [27,28].…”

Poly (ethylene oxide), PEO, which was used for a wide variety of applications is a flexible, crystalline, thermoplastic, water-soluble and non-ionic polymer. The most of studies on surfactant-modified activated carbon (SM-PAC) have been generally focused on the removal of contaminants. This study aims the preparation of PEO/(SM-PAC) composites, using solution-intercalation method. Firstly activated carbon was modified with cationic surfactant, Cetyltrimethylammonium Bromide (CTAB). Then PEO/(SM-PAC) composites were prepared using solution-intercalation method, with two different (SM-PAC) contents (1.0 and 2.0 wt.%). The characterization of the composites was made by X-ray diffraction (XRD), Fourier Infrared Spectroscopy (FT-IR), thermal analysis and tensile tests. The XRD patterns revealed that 2θ positions of the broad peaks belonging to the composites significantly shift to left compared with those of virgin PEO. The SEM images of the surfactant-modified powdered activated carbon (SM-PAC)/PEO composites prepared with the two different SM-PAC contents show that there is an intensive interaction between the CTA + ions of modified activated carbon surface and the polymer chains. From the tensile tests, it was found that the unmodified powdered activated carbon dispersed into the polymer matrix made the ductile polymer more brittle. However, the tensile and yield strengths of the composite, prepared with modified powdered activated carbon, have decreased, and the strain percent value has significantly increased.

“…However, the sol-gel approach is limited by the evolution of volatile byproducts and concomitant shrinkage when the hybrid is processed at elevated temperatures [4,5]. Alternatively, the incorporation of layered silicates can be used as inorganic components for the construction of nanostructured hybrid polymer composites [6,7]. Polymer-clay nanocomposites, as these materials are known, possess dramatically improved properties due to nanometre-sized dispersions of organically modified clay in the polymer matrix [8].…”

“…P(VdF-HFP) has excellent chemical stability due to VdF unit and plasticity due to HFP unit (Aravindan & Vickraman, 2007). However, gelled or plasticized P(VdF-HFP) based electrolytes exhibit drawbacks, such as increased reactivity with lithium metal electrode, solvent volatility and poor mechanical properties at high degree of plasticization (Jacob et al, 2003). In order to retain the mechanical properties of polymer gel electrolytes, the gel films have to be hardened either by chemical or physical curing (high energy radiation), which results in high processing costs.…”
