“…This decrease at higher FA content indicates agglomerates' formation, which initiates failure under stress. [ 66 ] This was supported by the SEM image of PA/ABS/18.5 FA composite where agglomerates were observed (Figure 13(G)). PA/ABS/S‐g‐M blend and PA/ABS/S‐g‐M/4.5 FA composites have almost similar Young's modulus and tensile strength values compared to PA/ABS blend and PA/ABS/4.5 FA composite, while composites with S‐g‐M at 9, 14, and 18.5 wt% FA loading show higher values than those without S‐g‐M.…”

In the present study, coal fly ash (FA) was used as a reinforcement in a thermoplastic matrix blend of polyamide 6/acrylonitrile‐butadiene‐styrene (PA/ABS). In the first part of this work, the as‐received FA (raw FA) was sieved with a 25 μm sieve to obtain FA with particle size less than 25 μm (FA). Then, the physicochemical properties of the raw FA and the FA were determined. Afterwards, FA was used to prepare a masterbatch of 20 wt% FA and 80 wt% PA by twin‐screw extrusion. Using this masterbatch, composites with different FA contents (4.5, 9, 14, and 18.5 wt%), with and without styrene‐(ethylene‐butylene)‐styrene grafted with maleic anhydride (SEBS‐g‐MA) (S‐g‐M), were produced by extrusion, which was followed by injection molding. Subsequently, several characterization techniques were performed to investigate the effect of FA loading and the S‐g‐M coupling agent on the structural, morphological, thermal, and mechanical properties of the developed composites. The results showed that incorporating FA particles in the matrix blend improved the thermal stability and crystallinity, the Young's modulus, the tensile strength, and torsional properties of the composites. In contrast, the addition of S‐g‐M coupling agent to the polymer composites improved the interfacial adhesion between FA particles and the matrix blend. This further enhanced the structural, morphological, thermal, and mechanical properties of the polymer composites. Overall, the use of FA as an inorganic filler improves the thermal and mechanical properties of polymer composites and shows a potential for promising applications.

“…The solvent uptake at equilibrium point decreases with increasing the loading of MnWO 4 in Cl‐SBR up to 7 phr loading. The free volume of the polymer matrix diminishes with the addition of nanoparticles, which inhibits the free movement and progress of the penetrant solvent inside the matrix . The increased surface area of reinforcing filler and consequent formation of strong interface coupled with the uniform dispersion of the nanofiller in the polymer matrix results in higher solvent resistance of the composite with 7 phr loading of MnWO 4 .…”

Novel nanocomposites based on chlorinated styrene butadiene rubber (Cl‐SBR) and manganous tungstate (MnWO4) nanoparticles have been developed using a simple and efficient open two roll mixing mill at room temperature. The nanocomposite containing varying loading of nanoparticles have been assessed for their spectral behavior, thermal, dielectric, flammability properties as well as the transport of aromatic solvents through their networks. Intermolecular interaction between the chlorinated moieties of SBR and MnWO4 has been revealed by Fourier transform infrared and UV‐Vis spectral studies. The uniform dispersion of nanoparticles and the crystalline peaks of MnWO4 nanoparticles in Cl‐SBR were observed from SEM and XRD, respectively. Thermogravimetric analysis and flame resistance analysis showed that the thermal stability and flame retardancy of Cl‐SBR increased with increasing ratio of MnWO4. The dielectric constant was much improved with the entire range of frequencies and the optimum dielectric constant was obtained for 7 phr loading. Transport parameters like the sorption, diffusion, and permeation coefficients were tabulated in terms of the nature of solvent, and the loading of nanoparticles. The solvent uptake reduced by the addition of nanoparticles up to 7 phr and thereafter the solvent uptake increases. The activation energy for the diffusion, sorption, and permeation process was evaluated and these values were highest in xylene at all filler loading. The mechanism of transport of the aromatic solvents through Cl‐SBR/MnWO4 nanocomposite was found to be anomalous mode. POLYM. COMPOS., 39:E1880–E1889, 2018. © 2018 Society of Plastics Engineers

In this study, we report the preparation of polymer blend nanocomposites based on chitin (CT)/cashew gum (CG) with various contents of magnetite nanoparticles (Fe3O4). The fabricated nanocomposites were characterised by FT infrared (FTIR), X‐ray diffraction (XRD), high‐resolution transmission electron microscopy (HRTEM), magnetic property (vibrating sample magnetometry (VSM)), differential scanning calorimetry (DSC), thermogravimetry (TGA) and impedance analyser. FTIR study revealed the characteristic absorption and shifts of peaks of the blend matrix, the shifts being attributed to the intermolecular interaction of Fe3O4 nanoparticles with CT/CG segments. The amorphous domain of the blend decreased with an increase in the concentration of nanoparticles was observed from XRD analysis. The HRTEM images showed the uniform arrangement of nanoparticles within the CT/CG network. VSM studies showed the ferromagnetic nature of the blend composite with an increasing saturation of magnetism with super‐paramagnetic behavior. DSC and TGA results revealed that the glass transition temperature and thermal stability of the composites were increased by the addition of magnetite nanoparticles. AC and dielectric properties were much improved in the entire range of frequencies due to the interaction with Fe3O4 nanoparticles. The role of nanoparticles on mechanical properties has been carefully studied. The tensile strength and hardness of magnetite filled nanocomposites become significantly higher in comparison to unfilled compounds and the nanocomposite with 10 wt. % of nanoparticles showed the maximum tensile strength.
