43. The quantitative analysis of nano-clay dispersion in polymernanocomposites by small angle X-ray scattering combined with electronmicroscopy

The main objective of this work is to propose a new approach for the quantitative analysis of the degree of dispersion of clay particles in the polymer matrix by small angle X-ray scattering (SAXS) combined with electron microscopy. Due to the low temperature processibility and good thermal stability, poly[(butylene succinate)-co-adipate] (PBSA) was chosen as a model polymer matrix for this study. The nanocomposites of PBSA with four different we...

44. Viscoelastic Properties of Clay‐Containing Nanocomposites ofThermotropic Liquid‐Crystal Polymer.

The nanocomposites of liquid-crystal polymer (LCP) with two different weight per cents of claywere preparedviathe melt extrusion method. To investigate the properties of the materials inthe linear and non-linear viscoelastic regions, both oscillatory and rotational tests were carriedout. The results showed that the nanocompositewith higher clay content exhibited an almostdefectless partially cross-linked structure com-pared to the nanocomposite w...

45. Influence of degree of intercalation on the crystal growth kinetics of poly [(butylene succinate)-co-adipate] nanocomposites

The influence of the degree of intercalation of polymer chains in the two dimensional silicate galleries on the crystallization behavior of poly[(butylene succinate)-co-adipate] (PBSA) is being reported on. The nanocomposites were prepared by melt-blending of PBSA and organically modified montmorillonite (OMMT) in a batch-mixer. Two different types of commercially available OMMTs, with different extents of miscibility of organic modifiers with PB...

Nonisothermal crystallization kinetics of poly(ethylene terephthalate) nanocomposites

This article reports the nonisothermal crystallization kinetics of poly(ethylene terephthalate) (PET) nanocomposites. The non-isothermal crystallization behaviors of PET and the nanocomposite samples are studied by differential scanning calorimetry (DSC). Various models, namely the Avrami method, the Ozawa method, and the combined Avrami-Ozawa method, are applied to describe the kinetics of the non-isothermal crystallization. The combined Avrami ...

Effect of Organoclay on the Orientation and Thermal Properties of Liquid-Crystalline Polymers

The preparation and thermal and thermo-mechanical properties of nanocomposites based on liquid-crystalline polymers (LCP) and organically-modified layered silicate (OMLS) is described. From XRD patterns, very little smectic ordering is present in the pure LCP; in the nanocomposites, the polymer chains tended to orient in the direction of the dispersed clay layers. According to the DSC results, during first heating, the first melting peak represe...

Effect of Organoclay on the Morphology andProperties of Poly(propylene)/Poly[(butylenesuccinate)-co-adipate] Blends

The effect of organically modified clay on the morphology and properties of poly(propylene)(PP) and poly[(butylene succinate)-co-adipate] (PBSA) blends is studied. Virgin and organoclaymodified blends were prepared by melt-mixing of PP, PBSA and organoclay in a batch-mixer at1908C. Scanning electron microscopy studies revealed a significant change in morphology ofPP/PBSA blend in the presence of organoclay. The state of dispersion of silicate lay...

Thermal and thermomechanical properties of poly[(butylene succinate)-co-adipate] nanocomposite

In this article the thermal and thermomechanical properties of neat poly[(butylene succinate)-co-adipate] (PBSA) and its nanocomposite are reported. Nanocomposite of PBSA with organically modified synthetic fluorine mica (OSFM) has been prepared by melt-mixing in a batch mixer. The structure of nanocomposite is characterized by X-ray diffraction patterns and transmission electron microscopic (TEM) observations that reveal homogeneous dispersion o...

Thermal and Thermo-mechanical Properties of Poly(ethylene terephthalate) Nanocomposites

In this study poly(ethylene terephthalate) (PET)/clay nanocomposites with two different weight percentages of montmorillonite (MMT) have been prepared by melt-extrusion technique. The X-ray diffraction (XRD) patterns and transmission electron microscopic (TEM) images reveal the formation of intercalated nanocomposites. The melting and crystallization behaviors of neat polymer and nanocomposite samples have been investigated by using both conve...
