Download file to see previous pages Iwahori, Ishiwata and Ishikawa (2003) argue that an understanding of the basic physical relationship in nano scale structural variables and micro scale properties of polymer nanocomposites is very important in this study. The development of polymer nanocomposites optimally using carbon nanotube and carbon nano fibre requires full comprehension of the processing structure property relationships. Aims of the Research The aim of the research is to develop improved materials properties in TPE-E nanocomposites using the processing structure property relationships. The research will develop the following objectives which will be investigated: 1. To optimally disperse the nanofillers into the TPE-E via melt processing and reactive extrusion (Nanocomposite processing). 2. To develop a complete understanding of thee processing morphology properties in the nanocomposite system, most importantly the interplay between TPE-E nanophase domains and an engineered low and high aspect ratio nanofillers (morphology and properties) 3. To comprehensively determine the mechanical and electrical performance of these nanocomposites. Literature Review According to Kotsilkova (2005) and Dobrzai (2002), an overview of the synthesis and characterization methods of nanocomposite is important in clay layer orientation and its dispersion in various nanocomposites. Many previous researches have tried to relate the clay orientation to the enhancement of materials properties from a qualitative viewpoint. Quantitative studies are may be limited because of lack of techniques to quantitatively determine the three dimensional orientation of structures in nanocomposites. In one of the recent developed techniques of determining the three dimensional orientation, the effect of compatibilizer concentration upon the orientation and dispersion of structures in polyethylene nanocomposite films was found to be thickness. An increase in concentration showed a corresponding decrease in orientation of clay layer along the thickness of the film (Bevis 1999; Suprakas, Kazuaki & Masami 2003; Liu, Hoa & Pugh 2004). Other researchers have explored ways of using commercially available products to create new materials by synthesising TPE-E to register a wide range of property improvements. The TPE-E synthesis may comprise melt compounding and reactive extrusion using organic clays as nanofillers. Hybrid composition morphology within nanocomposites, when treated in various processes, demonstrates the maximum range of properties of materials. The various methods of attaining a wide range of property enhancements are the organo clay nanofiller surface modification, additional processing parameter and the TPE-E hard and soft segment composition ratio together with the organ clay filler aspect. These material properties are governed by the manipulation of these variables and assessing the sizes of intercalate molecules (Laird & Fleming 1999; Mani et al. 2005). Colbert and Smalley (2002) argue that many other studies have focused on the microstructure processing and property relationships, which have helped in knowledge development and comprehensive understanding of these processes to develop more innovative products both for personal and commercial purposes.

...Research Paper There are so many terms that are used to describe the relationship where one partner is domineered bythe other. Domestic abuse is very common in so many homes. The homes report the various forms that domestic abuse manifests itself. The four broad categories include physical, emotional, sexual and financial abuse. They all work hand in hand at destroying the psychology of the person being abused. There are very many factors that have contributed to the growth of domestic abuse all over the world. They include stressful situations, substance abuse and many psychological disturbances experienced by the abuser. What is clear is that domestic abuse affects both male and females in any union (Dutton, p 12). For...

Processing Petroleum
...molecular makeup of crude oil varies from location to location as mentioned above however the chemical elements required to form crude oil vary over a fairly narrow margin. (Speight, 1999) The major hydrocarbon components of crude oil include paraffins, naphthenes, aromatics and asphaltics which display consistency in their presence in crude oil. The variation in these hydrocarbon components determines the exact properties of the crude oil in question. (Hyne, 2001) Crude oil contains a number of lighter more usable factions such as HFO, LFO, diesel, gasoline and a number of components for isomers of various kinds, asphalt etc. These factions can only be separated if crude oil is subjected to various...

.... It was noted that surfactant’s decomposition can be lowered if the process is conducted at approx. 2600C but not at usual 2800C. MMT is not the only substrate that can be used in the described processes. Cloisite 10-A is an interesting example leading to thermally stable nanocomposites. By altering the structure of Cloisite 10-A it was possible to afford products more thermally stable then in case of montmorillonite. Taking into account the listed examples from literature, it can be stated that preparation of modified organoclays to melt blend with different grades of TPE-E (Block copolyester thermo platic elastomers) using extruder...

Reactive extrusion of TPE-E nanocomposites
...? Reactive Extrusion of TPE-E Nanocomposites Introduction TPEE is resistant to oil and chemical as well as having low temperature properties. These properties make it to be a good compound for use in automobile, electric and electronic applications. Chloroprene was earlier used for automobiles but it was replaced with TPEE because it has low durability. In addition, TPEE is widely used in Europe and North America because of its lightweight and its resistant properties to fatigue and chemicals. TPEE is produced through extrusion blowing at its melt state thus the resin must have good melt viscosity and tension in order to produce thickness...
