Available in PDF, EPUB and Kindle. Book excerpt: This work focuses on the relationship between the morphology of filled rubber and its behavior at small and large deformations. Composites made from vinyl terminated polydimethylsiloxane and different fumed silicas were prepared. Filler concentration ranged from 0 to 40 phr (part of silica per hundred parts of PDMS). Small deformation tests were done using oscillatory shear and showed coupling of the filler and crosslinking effects as high crosslinking density while the effects are more or less independent at low crosslinking levels. Keywords: Polydimethylsiloxane, Silica filler, Rheology, PDMS, Elastomers and rubber, Silanols, Hydrosilation, Fluid mechanics, Silicone, Reinforcement. (JG).

Available in PDF, EPUB and Kindle. Book excerpt: Polymerie materials have been replacing other conventional materials like metals, glass and wood in a number of applications. The use of various types of fillers incorporated into the polymer has become quite common as a means of reducing cost and to impart certain desirable mechanieal, thermal, electrieal and magnetic properties to the polymers. Oue to the energy crisis and high priees of petrochemieals, there has been a greater demand to use more and more fillers to cheapen the polymerie materials while maintaining and/or improving their properties. The advantages that filled polymer systems have to offer are normally offset to some extent by the increased complexity in the rheological behavior that is introduced by the inclusion of the fillers. Usually when the use of fillers is considered, a compromise has to be made between the improved mechanieal properties in the solid state, the increased difficulty in melt processing, the problem of achieving uniform dispersion of the filler in the polymer matrix and the economics of the process due to the added step of compounding. It has been recognized that addition of filler to the polymer brings a change in processing behavior. The presence of the filler increases the melt viscosity leading to increases in the pressure drop across the die but gives rise to less die swell due to decreased melt elasticity.

Available in PDF, EPUB and Kindle. Book excerpt: This work focuses in the basic understanding of reinforcement and the relationship between the morphology of the material and its rheological behavior. Mixtures of polydimethylsiloxanes and different fumed silicas were tested under oscillatory shear. The silica structure was kept constant by using a single initial product. Only the surface chemistry was changed. All samples showed a strong strain dependence, and the frequency dependence changed dramatically with silica concentration. Agglomeration increases with silica concentration, amount of silanols on the silica surface and polymer molecular weight. All these observations as well as the relaxation of the different materials are explained with a model in which agglomeration takes place through intermediate chains that link the aggregates to one another. However, low molecular weight suspension showed a different behavior. This behavior was related to the absence of entanglements and low probability of bridging chains. Keywords: Polydimethylsiloxane, Silica filler, Rheology, Fluid mechanics, Polymer melts, Elastomers and rubbers. (JG).

Download or read book Polymer Composite Materials Interface Phenomena Processes written by Y. Ivanov and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 176 pages. Available in PDF, EPUB and Kindle. Book excerpt: New technologies demand new materials. Polymer composites, with their wide range of possible fillers and polymers, open the way to an enormous range of materials with differing chemical, physical, and mechanical properties. The ultimate goal of polymer composite research is to formulate procedures that will lead to the design of composites with preset, i.e. specified, properties. Based on many years' experience in the field, the authors prepare the way towards just such a design procedure. The key element is the analysis and classification of the state of the filler-polymer interfaces from the point of view of their acid-base adsorption interactions. These interfacial phenomena play a pivotal role in determining overall properties of the composite: its rheological behaviour, its structural properties, catalytic effects in polymerization and polycondensation, and other technological characteristics. The book discusses and evaluates the extensive previous research scattered throughout the literature in Eastern Europe and the West, presents numerous experimental studies, and sets new benchmarks for the analysis of polymer composites. The book is required for researchers wanting to keep abreast of the progress in the burgeoning fields of polymer analysis and design.

This book was released on 2014-11-20 with total page 318 pages. Available in PDF, EPUB and Kindle. Book excerpt: Advances in Polymer Science enjoys a longstanding tradition and good reputation in its community. Each volume is dedicated to a current topic and each review critically surveys one aspect of that topic, to place it within the context of the volume. The volumes typically summarize the significant developments of the last 5 to 10 years and discuss them critically, presenting selected examples, explaining and illustrating the important principles and bringing together many important references of primary literature. On that basis, future research directions in the area can be discussed. Advances in Polymer Science volumes thus are important references for every polymer scientist, as well as for other scientists interested in polymer science - as an introduction to a neighboring field, or as a compilation of detailed information for the specialist.

Download or read book Composites Materials for Food Packaging written by Giuseppe Cirillo and published by John Wiley & Sons. This book was released on 2018-05-22 with total page 462 pages. Available in PDF, EPUB and Kindle. Book excerpt: The novel insights, as well as the main drawbacks of each engineered composites material is extensively evaluated taking into account the strong relationship between packaging materials, environmental and reusability concerns, food quality, and nutritional value. Composites, by matching the properties of different components, allow the development of innovative and performing strategies for intelligent food packaging, thus overcoming the limitations of using only a single material. The book starts with the description of montmorillonite and halloysite composites, subsequently moving to metal-based materials with special emphasis on silver, zinc, silicium and iron. After the discussion about how the biological influences of such materials can affect the performance of packaging, the investigation of superior properties of sp2 carbon nanostructures is reported. Here, carbon nanotubes and graphene are described as starting points for the preparation of highly engineered composites able to promote the enhancement of shelf-life by virtue of their mechanical and electrical features. Finally, in the effort to find innovative composites, the applicability of biodegradable materials from both natural (e.g. cellulose) and synthetic (e.g. polylactic acid – PLA) origins, with the aim to prove that polymer-based materials can overcome some key limitations such as environmental impact and waste disposal.
