“…The CH-asymmetric (2930-2970 cm −1 ) and symmetric stretching (2840-2860 cm −1 ) are clearly seen in polyolefin-based compatibilizers. The characteristic peak of grafted anhydride, which is too small to observe, is found at 1843 cm −1 (Kouini and Serier 2012;Wang et al 1999). In PS-g-MA compatibilizer, the band present at the 671 cm −1 is the δ c = c of the phenyl group (Li et al 2002).…”

“…Kitayama et al (1991) prepared triblock copolymer of PMMA and polyisobutylene by anionic polymerization and reported that block copolymer formed was rigid spherical particles, which can be used as elastomer. Kouini and Serier (2012)) found that the impact property increased with the incorporation of PP-g-MA in PP/PA66 nanocomposites. TPO/PP-g-MA/MMT nanocomposites prepared by Kim et al (2007aKim et al ( , 2007b revealed that the modulus and yield strength enhanced by increasing PP-g-MA/organoclay ratios.…”

“…However, copolymers usually show little contribution to the strength and stiffness of polymer blends because of their low molecular weight compared with that of the bulk polymer, resulting in a decrease of strength and Young's modulus. In addition, block or grafted copolymers are difficult to synthesize as well as being expensive for industrial production . Therefore, it is urgent to seek for a new potential compatibilization strategy at low cost for the industrial field.…”

Compatibilization of immiscible nylon 6/poly(vinylidene fluoride) blends using graphene oxides

A new strategy to compatibilize immiscible blends is proposed, using graphene oxide (GO) nanosheets taking advantage of their unique amphiphilic structures. When 0.5 or 1 wt% GOs were incorporated in immiscible nylon 6/poly(vinylidene fluoride) (PVDF) (90/10 wt%) blends, the dimension of PVDF dispersed particles was markedly reduced and became more uniform, revealing a well‐defined compatibilization effect of GOs on the immiscible blends. Correspondingly, the ductility of the compatibilized blends increased several times compared with uncompatibilized immiscible blends. In order to explore the underlying compatibilization mechanism, Fourier transform infrared and Raman spectra were applied to suggest that the edge polar groups of GOs can form hydrogen bonds with nylon 6 while the basal plane of GOs can interact with electron‐withdrawing fluorine on PVDF chains leading to the so‐called charge‐transfer C–F bonding. In this case, GOs exhibit favorable interactions with both nylon 6 and PVDF phase, therefore stabilizing the interface during GO migrations from PVDF/GO masterbatch to nylon 6 phase, which can minimize the interfacial tension and finally lead to compatibilization effects. Obviously, this work may open a broad prospect for GOs to be widely applied as a new compatibilizer in industrial fields. © 2012 Society of Chemical Industry

In recent years, the application of polymer nanocomposites has been enormously increased, particularly in aerospace and automotive sector due to its lightweight and high specific strength. In this study, nanocomposite materials with polypropylene (PP) matrix and Cloisite 30B (C30B) as reinforcing nanofiller with Elvaloy AC 3427 (EA) as compatibilizer were manufactured by melt intercalation technique with the aid of twin-screw extruder (TSE). The C30B with EA was reinforced in the PP matrix at 1, 2, 3 and 5 wt%. The PP/C30B/EA nanocomposites were processed in TSE with different barrel zones such as conveying zone, melting zone, mixing zone and plasticizing zone which helps in achieving homogenous dispersion of C30B in PP matrix. The processing parameters of TSE are twin-screw speed (65 r/min), volumetric feeder’s screw speed (7 r/min), degassing zone pressure (40 mmHg), cooling length (50 cm) and humped temperature profile (170–220°C). The processed PP/C30B/EA was characterized using X-ray diffraction (XRD) for studying intercalation/exfoliation structure formation and transmission electron microscope (TEM) for studying the dispersion of C30B in PP matrix. The thermal characterization of PP/C30B/EA nanocomposites was investigated by differential scanning calorimetry (DSC), thermogravimetric analysis (TGA) and dynamic mechanical analysis (DMA). The addition of C30B at 5 wt% to PP/C30B/EA nanocomposites increased the DSC, TGA and DMA properties.
