O-Muscovite/PP Layered Silicate Nanocomposites were prepared via melt compounding using different filler content. Muscovite was organomodified with Cetyldimethylethylammonium bromide (CEDAB). The thermal and mechanical properties of nanocomposites, based on polypropylene (PP) filled by organo-clay (O-Muscovite), were studied in order to clarify the effect of O-Muscovite on the O-Muscovite/PP layered silicate nanocomposites by WAXD, TEM and DSC analyses. XRD indicated that O-Mica layers were intercalated and dispersed into polypropylene. Analysis of test data shows that, addition of organo-clay improved mechanical properties of O-Mica/PP nanocomposites. With the incorporation of 5 wt% O-Mica (optimal filler loading) into polypropylene Izod impact increased to 23%. The DSC analyses have shown that the influence of organo-clay on the thermal properties of material was significant in composites with O-Mica as fillers, compared to virgin PP. The enhancements of properties can be caused by the formation of intercalated and exfoliation nanocomposite structure at this clay content and stronger interaction of O-Mica with polymer matrix. At a higher filler loading, degradation in mechanical properties maybe attributes to the formation of agglomerated clay tactoids. O-Muscovite/PP Layered Silicate Nanocomposites were prepared via melt compounding using different filler content. Muscovite was organomodified with cetyltrimethylammoniumbromide (CTAB). The thermal and mechanical properties of nanocomposites, based on polypropylene (PP) filled by organo-clay (O-Muscovite), were studied in order to clarify the effect of O-Muscovite on the O-Muscovite/PP layered silicate nanocomposites by WAXD, TEM and DSC analyses. XRD indicated that O-Mica layers were intercalated and dispersed into polypropylene. It was found that the mechanical and thermal properties of organo-clay nanocomposite possess better properties as compared to the unmodified clay nanocomposites. The reason was partly due to the formation of intercalated and exfoliation nanocomposite structure at this clay content and stronger interaction of O-Mica with polymer matrix.

AbstractNanocomposites based on biodegradable poly(e-caprolactone) (PCL) and layered silicates (montmorillonite) modified by various alkylammonium cations were prepared by melt intercalation. Depending on whether the ammonium cations contain non-functional alkyl chains or chains terminated by carboxylic acid or hydroxyl functions, microcomposites or nanocomposites were recovered as shown by X-ray diffraction and transmission electron microscopy. Mechanical and thermal properties were examined by tensile testing and thermogravimetric analysis. The layered silicate PCL nanocomposites exhibited some improvement of the mechanical properties (higher Young’s modulus) and increased thermal stability as well as enhanced flame retardant characteristics as result of a charring effect. This communication aims at reporting that the formation of PCL-based nanocomposites strictly depends on the nature of the ammonium cation and its functionality, but also on the selected synthetic route, i.e. melt intercalation vs. in situ intercalative polymerization. Typically, protonated w-aminododecanoic acid exchanged montmorillonite allowed to intercalate ε -caprolactone monomer and yielded nanocomposites upon in situ polymerization, whereas they exclusively formed microcomposites when blended with preformed PCL chains. In other words, it is shown that the formation of polymer layered silicate nanocomposites is not straightforward and cannot be predicted since it strongly depends on parameters such as ammonium cation type and functionality together with the production procedure, i.e., melt intercalation, solvent evaporation or in situ polymerization.

Purpose The purpose of this paper is to investigate the influence of binder effect on tribological behavior of brake friction composite materials: a case study of phenolic resin modified by N-Methylaniline. Design/methodology/approach Four different friction materials have been fabricated by varying modified phenolic resin content. The samples were prepared by the conventional powder metallurgy methods following ball milling, mixing, pre-forming, hot pressing and post-curing processes. Thermogravimetric analysis was used to determination of the degradation mechanism of organic components and study of thermal stability of the samples. A friction test was carried out in dry conditions using a vertical tribometer. Analysis of worn surfaces was performed using a scanning electron microscope. Findings The experimental results revealed that the sample containing 25 Wt.% phenolic resin has good mechanical and thermal properties with stable friction characteristics. Originality/value This paper presents the effect of N-methylaniline modified phenolic resin on friction composites to improve tribological performance by its thermal properties.
