A novel modification on melt intercalation via exothermal MMT

Journal of Applied Polymer Science, 2004
AbstractThis article presented a novel modification on the melt intercalation. Montmorillonite (MMT) with exothermal enthalpy effect was prepared by the compounding of MMT with AIBN in solution. An exfoliated polystyrene (PS)/MMT nanocomposites could be obtained by the introduction of exothermal MMT via melt mixing, and the comparison with the ...

Manufacturing Issues of Polypropylene Nanocomposite by Melt Intercalation Process

Materials Today: Proceedings, 2017
Abstract Polymer nanocomposites are gaining interest among the researchers due to their widespread applications. Melt intercalation method with the aid of twin screw extruder was used for the production of polymer nanocomposites. This paper covers the detailed discussions about the manufacturing of Closite30B reinforced with polypropylene by ...

Nonisothermal crystallization behavior of melt‐intercalated polyethylene‐clay nanocomposites

Journal of Applied Polymer Science, 2006
AbstractThe influence of nanoclay particles on the nonisothermal crystallization behavior of intercalated polyethylene (PE) prepared by melt‐compounding was investigated. It is observed that the crystallization peak temperature (Tp) of PE/clay nanocomposites is slightly but consistently higher than the neat PE at various cooling rates.

The Enhanced Melt Intercalation of Polyethylene Using Exothermal Montmorillonite

Journal of Macromolecular Science, Part B, 2011
Exothermal montmorillonite (EMMT) was prepared and used in the preparation of HDPE composites in which the EMMT was intercalated. Compared with the ODA modified montmorillonite (OMMT), EMMT exhibited better intercalation behavior during melt compounding, resulting in similar tensile modulus and better tensile strength and elongation at break of the ...

Solidlike transition of melt‐intercalated biodegradable polymer/clay nanocomposites

Journal of Polymer Science Part B: Polymer Physics, 2003
AbstractSynthetic biodegradable aliphatic polyester (BAP) intercalated into organoclay was prepared by melt compounding, and its solidlike characteristics were investigated via several rheological test modes: steady shear rotation, oscillation, and creep testing.

Polymer Melt Intercalation in Clay Modified by Diblock Copolymers

Macromolecular Theory and Simulations, 2004
AbstractSummary: The thermodynamic equilibrium in a melt of homopolymer C mixed with clay modified by a diblock copolymer AB is considered in theory. It is assumed that mixing is carried out in two stages. At first, the diblock copolymer penetrates into the interlayers formed by long clay sheets. Then, the clay with adsorbed diblock copolymer chains is

Melting of the intercalated layers in Csx(THF)yC24

Synthetic Metals, 1988
Abstract The thermal behaviour of the first stage Cs x (THF) y C 24 ternary graphite intercalation compound has been studied in the range 40 to 300 K. The intercalant is “liquid”-like at room temperature and the THF molecules are probably exchanging between adjacent complexes, thus permitting the non integral THF/Cs ratio. In the range 248 to 233 K,

Intercalation and Grafting of Vermiculite with Octadecylamine Using Low-temperature Melting

Clays and Clay Minerals, 2003
AbstractOctadecylamine (ODA) was used to intercalate a fine-grained and a coarse-grained fraction of natural Mg-vermiculite (VER) using a low-temperature melting procedure. Mixtures of Mg-vermiculite fractions and powdered ODA in the molar ratios of 2:1, 1:1, 1:2 and 1:6 were homogenized and heated for 1, 3, 15 and 30 h at 80°C to prepare intercalated ...

Study of Interlayer Spacing Collapse During Polymer/Clay Nanocomposite Melt Intercalation

Journal of Nanoscience and Nanotechnology, 2008
The influence of the chemical structure of alkylammonium organo-modifying montmorillonite clays on the ability to form nanocomposites by melt blending, depending on the processing temperature and the organoclay thermal treatment, has been investigated.

Reversible De-Intercalation and Intercalation Induced by Polymer Crystallization and Melting in a Poly(ethylene oxide)/Organoclay Nanocomposite

Langmuir, 2005
Semicrystalline polymer/layered silicate nanocomposites were prepared by solution blending of a low molecular weight poly(ethylene oxide) (PEO) with an organically modified montmorillonite, Cloisite 10A (C10A). The intercalation morphology was studied by temperature-dependent synchrotron wide-angle X-ray diffraction (WAXD).
