“…The improved thermal stability of PP‐AMUF nanocomposites may be attributed to the adsorption of the volatile decomposition products generated during the thermal degradation on the surface of AMUF fibers, thereby, resulting in delayed degradation of the PP matrix. Similar findings for mullite reinforced epoxy and polyester nanocomposites have also been reported earlier . The char yield of the nanocomposites increased with increase in AMUF content.…”

“…In addition, mullite can be used in packaging materials and memory devices . Recently, mullite fibers (MUF) have been used as nanofiller for the development of epoxy and unsaturated polyester resin nanocomposites due to high thermal stability, high oxygen resistance, and low dielectric constant . To the best of our knowledge, no reports are available on the development of mullite fiber reinforced PP nanocomposites.…”

This study describes the reinforcement effect of surface modified mullite fibers on the crystallization, thermal stability, and mechanical properties of polypropylene (PP). The nanocomposites were developed using polypropylene-grafted-maleic anhydride (PP-g-MA) as compatibilizer with different weight ratios (0.5, 1.0, 1.5, 2.5, 5.0, and 10.0 wt %) of amine functionalized mullite fibers (AMUF) via solution blending method. Chemical grafting of AMUF with PP-g-MA resulted in enhanced filler dispersion in the polymer as well as effective filler-polymer interactions. The dispersion of nanofiller in the polymer matrix was identified using scanning electron microscopy (SEM) elemental mapping and transmission electron microscopy (TEM) analysis. AMUF increased the Young's modulus of PP in the nanocomposites up to a 5 wt % filler content, however, at 10 wt % loading, a decrease in the modulus resulted due to agglomeration of AMUF. The impact strength of PP increased simultaneously with the modulus as a function of AMUF content (up to 5 wt %). The mechanical properties of PP-AMUF nanocomposites exhibited improved thermal performance as compared to pure PP matrix, thus, confirming the overall potential of the generated composites for a variety of structural applications. The mechanical properties of 5 wt % of AMUF filled PP nanocomposite were also compared with PP nanocomposites generated with unmodified MUF and the results confirmed superior mechanical properties on incorporation of modified filler.

Recently, many inorganic solid wastes have accumulated as a byproduct in several industries and their storage is one of the major problems. Among these wastes, steel slag has attracted attention to utilize with different purposes. In this study, original steel slag (OS) and modified steel slag (MS) were evaluated as a filler to prepare low-cost epoxy composites. The effect of components on the properties of steel slag/ epoxy composites (SECs) was investigated with various analyses and tests. Physicomechanical and thermal properties of the SECs were compared with each other and neat epoxy resin (ER). Good dispersion of OS and MS in the ER matrix was determined with Xray diffraction (XRD) pattern and scanning electron microscopy (SEM). Tensile strength, Young modulus, and hardness values of the SECs were enhanced after modification of OS. Any change on adhesion and corrosion resistance of the SECs was not observed; however water sorption percent was increased with the addition of components. As per thermogravimetric analyses (TGA) and vicat softening temperature (VST) analyses, SECs cured with anhydride showed higher decomposition temperature than the other hardener.

“…Mullite is the stable ceramic material with the combination of silica and alumina (3Al 2 O 3 :2SiO 2 ), exhibits 1D fibrous morphology. Mullite was used as a nanofiller for the development of epoxy, unsaturated polyester, and polybenzoxazine matrices due to its high thermal stability, high oxygen resistance, and low dielectric constant . To the best of our knowledge, no reports are available on the 2D nanostructure of mullite.…”

In the present work, we studied the reinforcement effect of mullite nanosheets (MNs) on the properties of polypropylene (PP)/maleic anhydride graft ethylene‐vinyl acetate (EVA‐g‐MA) blend matrix. MNs have been prepared in the presence of polyvinylpyrrolidone (PVP) as the macromolecular surfactant through the sol–gel process followed by a thermal annealing method. The sheet‐like morphology of mullite was confirmed by transmission electron microscopy analysis. The surface of the MNs was modified using 3‐aminopropyltriethoxysilane. One weight percent of amine‐functionalized MNs (AMNs) improved the impact strength of PP/EVA‐g‐MA blend matrix, which is about 52%. Melt rheology analysis resulted that the nanocomposite exhibited a viscous behavior up to 2.5 wt % of AMNs and above the content ensued a viscoelastic solid‐like behavior. X‐ray diffraction analysis showed a complete dispersion of AMNs in the PP/EVA‐g‐MA blend matrix. TEM analysis confirmed that the MNs sheets are residing mostly in EVA‐g‐MA phase and the interface of PP/EVA‐g‐MA blend. © 2019 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2019, 136, 48233.
