Polymer layered silicate nanocomposites are very prevailing in both basic research and industrialdevelopment, among them montmorillonite (MMT) provide the most significant applied value. In thisstudy, structures and properties of various organic/inorganic nanocomposites of low-densitypolyethylene (LDPE) containing MMT and LDPE grafted maleic anhydride/montmorillonite (LDPE-g-MA/MMT) were investigated. Mechanical properties and thermal stability of LDPE/MMT and LDPE-g-MA/MMT nanocomposites were examined. Samples of LDPE/MMT and LDPE-g-MA/MMT nanocompo-sites were fabricated with twin-screw extruder and injection molding machine in accordance with thestandard test specimens. Furthermore, tensile, impact, bending, hardness, DSC, TGA, and SEMexaminations were performed to establish the structure–properties relationships. The mechanicalproperties significantly improved when the proper amounts of MMT and MA-grafted materials wereadded to LDPE. This improvement in properties is mainly due to the compatibilizing effect of MA grafts

The development of fire retardant for wire and cable sheathing materials has oriented toward low smoke and halogen-free flame retardant technology to achieve better safety for electrical equipment and devices and to satisfy standards. However, many polymer flame resistance materials require a very high proportion of metal hydrate filler within the polymer matrix (60 wt%) to achieve a suitable level of flame resistance, which may lead to inflexibility, poor mechanical properties and problems during compounding and processing. In this study, the alumina trihydrate (ATH) was added to montmorillonite (MMT) as the halogen-free flame retardant of ethylene-vinyl acetate (EVA) copolymer, with various ratios of EVA/ATH/MMT. The prepared nanocomposites were characterized through various techniques of XRD, tensile test, DSC analysis, TGA, LOI evaluation, and FE-SEM to explore the effects of organic modified clay (OMMT) and the layer distance on the mechanical, thermal, and flame resistance properties. In the XRD examinations, the layer-distance of MMT increased from 1.27 to 1.96 nm when polymer was added to the octadecylamine modified MMT. The best tensile strength was obtained at 3 wt% MMT. In addition, the halogen-free flame resistance grade of EVA containing 3 wt% OMMT and 47 wt% ATH revealed the best elongation and fire resistance (LOI = 28). The tensile and flame resistance properties of the nanocomposites were also significantly improved.
