Carbonate and stearate intercalated layered double hydroxides were used as fillers to prepare polymer micro-and nano-composites respectively. The stearate modified starting material was a bilayer-intercalated clay. During melt compounding excess stearates were released and the clay reverted to a monolayer-intercalated form. The exuded stearate acted as a lubricant lowering the melt viscosity of poly(ethylene-co-vinyl acetate) and linear low density polyethylene matrices. Strong hydrogen bond interactions between the chains of poly(ethyleneco-vinyl alcohol) and the clay platelet surfaces overwhelmed the lubricant effect and caused an increase in the melt viscosity of this matrix. The notched Charpy impact strength of this composite was almost double that of the neat polymer. It appears that this can be attributed to the ability of the highly dispersed and randomly dispersed nano-sized clay platelets to promote extensive internal micro-cavitation during impact loading. This creation of a large internal surface area provided the requisite energy dissipation mechanism.

“…a showed two endothermic crystallite melting peaks at 61 ± 1°C and 117 ± 1°C, respectively. The peak at 117 ± 1°C range which is reported to correspond to the melting of polyethylene segment is observed to be retained in the 2nd heating cycle in Fig. b.…”

“…c, can be attributed to low degree of crystallinity developed on account of crystallization during cooling cycles only. No prominent shift in crystallization temperature ( T c ) as well as melting temperature ( T m ) can be ascribed to absence of chemical interaction between EVA and MWCNT and reduction in nucleation ability of carbon nanotubes due to the confinement of EVA chains on their surface .…”

“…A similar work by Pal et al on the same polymer is on the dielectric properties of EVA and its possible application as capacitors [36,37]. Even though there are several reports [49][50][51] on the effect of reinforcement on differential scanning calorimetric properties (crystallization and crystallite melting pattern) and dielectric response of EVA nanocomposites, majority of them are on plastic grade EVA with VA content less than 40%. However, rubbery grade EVA with VA content in 40-60% range have rarely been investigated in details in this respect [60].…”

Homogeneous multiwalled carbon nanotube/montmorillonite hybrid filler (HMM) dispersion was prepared by co‐ultrasonication and was subsequently used to prepare ethylene‐co‐vinyl acetate (EVA) nanocomposites by solution blending method. XRD and TEM analysis of HMM confirm significant interaction between the montmorillonite (MMT) layers and multiwalled carbon nanotubes (MWCNT) in line with previous reports. Analysis of the nanocomposites shows the constituent fillers to be homogeneously dispersed in EVA matrix. Mechanical properties of neat EVA are remarkably improved with HMM content up to 3 wt% followed by reversion. Maximum improvement observed in tensile strength, elongation at break, and toughness are 424%, 109%, and 1122%, respectively. Results show maximum thermal stability at 4 wt% and best dielectric response at 1 wt% HMM content. Exceptional mechanical and dielectric properties of EVA nanocomposites attained may be attributed to homogeneous dispersion of fillers and improved polymer–filler interaction. Comparison shows excellent synergy between MWCNT and MMT towards mechanical reinforcement of EVA. POLYM. ENG. SCI., 58:1155–1165, 2018. © 2017 Society of Plastics Engineers

“…However, because of its low tensile strength, ease of igniting and very bad smoke emission while burning, its practical application has been strictly limited [4][5][6]. To overcome these problems and in order to achieve the required strength, flame retardancy, and thermal stability, several studies have been conducted [7][8][9][10].…”

Ethylene vinyl acetate (EVA) and poly(styrene-co-butyl acrylate)/organo-silica nanocomposites were prepared by melt blending in a twin screw bara-bender. The structural, morphological, thermal, and mechanical properties of the prepared nanocomposites were investigated using Fourier Transform Infrared, Field Emission Scanning Electron Microscopy, and thermal analysis (TGA and DSC). In addition, the tensile properties were identified. It was found that addition of 5% poly(styrene-cobutyl acrylate)/organo-silica to the matrix of EVA has improved the tensile strength of the nanocomposite by 29%. The thermal stability of the nanocomposites has been improved and the residue (char % at 5008C) reaches its maximum value. POLYM.
