This book was released on 2006 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The present study focuses on using this novel heating technology to carryout highly energy intensive polymerization process. L-lactic acid polymerization was carried out under microwave heating. High molecular weight poly (l-lactic acid) was synthesized with or without using Sn-octoate catalyst. Polymerization time was reduced to a few hours under microwave heating compared to 24 to 48 hours required by conventional polymerization process. Increase in the reaction rates were attributed to both thermal and non thermal heating effects of microwave. Copolymeric blend of immiscible polymers like PLLA and PGA were also prepared using microwave heating, resulting in blends which exhibited uniformity, block copolymerization and good compatibility. Insitu synthesis of hydroxyapatite during lactic acid polymerization under microwave heating resulted in high molecular weight PLLA with nano to micron scale hydroxyapatite particles embedded in the matrix. Degradation of low molecular weight microwave synthesized PLLA showed bulk degradation and have been shown as potentials for drug delivery applications.

Download or read book Algae Based Polymers Blends and Composites written by Khalid Mahmood Zia and published by Elsevier. This book was released on 2017-06-19 with total page 740 pages. Available in PDF, EPUB and Kindle. Book excerpt: Algae Based Polymers, Blends, and Composites: Chemistry, Biotechnology and Material Sciences offers considerable detail on the origin of algae, extraction of useful metabolites and major compounds from algal bio-mass, and the production and future prospects of sustainable polymers derived from algae, blends of algae, and algae based composites. Characterization methods and processing techniques for algae-based polymers and composites are discussed in detail, enabling researchers to apply the latest techniques to their own work. The conversion of bio-mass into high value chemicals, energy, and materials has ample financial and ecological importance, particularly in the era of declining petroleum reserves and global warming. Algae are an important source of biomass since they flourish rapidly and can be cultivated almost everywhere. At present the majority of naturally produced algal biomass is an unused resource and normally is left to decompose. Similarly, the use of this enormous underexploited biomass is mainly limited to food consumption and as bio-fertilizer. However, there is an opportunity here for materials scientists to explore its potential as a feedstock for the production of sustainable materials. - Provides detailed information on the extraction of useful compounds from algal biomass - Highlights the development of a range of polymers, blends, and composites - Includes coverage of characterization and processing techniques, enabling research scientists and engineers to apply the information to their own research and development - Discusses potential applications and future prospects of algae-based biopolymers, giving the latest insight into the future of these sustainable materials

Available in PDF, EPUB and Kindle. Book excerpt: The first reports on the application of microwaves in organic synthesis date back to 1986, but it was not until the recent introduction of specifically designed and constructed equipment, which countered the safety and reproducibility concerns, that synthetic application of microwaves has become established as a laboratory technique. Microwave assisted synthesis is now being adopted in many industrial and academic laboratories to take advantage of the novel chemistry that can be carried out using a variety of organic reaction types. This book demonstrates the underlying principles of microwave dielectric heating and, by reference to a range of organic reaction types, it’s effective use in synthetic organic chemistry. To illustrate the impact microwave assisted organic synthesis can have on chemical research, case studies drawn mainly from the pharmaceutical industry are presented.

Download or read book Polymer Nanoclay Composites written by Stephan Laske and published by William Andrew. This book was released on 2015-01-09 with total page 194 pages. Available in PDF, EPUB and Kindle. Book excerpt: There is a major lack of fundamental knowledge and understanding on the interaction between a filler and the polymer matrix. When it comes to nanoscale fillers, such as layered silicates, carbon nanotubes, graphene or cellulose nanofibers it is even more important to know accurate structure-property relationships as well as identifying the parameters influencing material behavior. The reason for the lack of knowledge on how to process nanocomposites and why there are so few applications is that several scientific fields are affected and a joint effort of those scientific communities involved is necessary – starting from the filler manufacturing or pre-processing over polymer chemistry to the polymer processing. In Polymer Nanoclay Composites, all involved scientific areas are viewed together for the first time, providing an all-embracing coverage of all stages of polymer clay nanocomposites processing from lab-scale to industrial scale – stages from the raw material over manufacturing of polymer clay nanocomposites to characterization and the final products. Readers will gain insight in the physical/chemical pre-processing of layered silicates and their incorporation into a polymer matrix using sophisticated technologies (such as advanced compounding) as well as in real-time quality control of the nanocomposite production and future prospects. The book also describes nanotoxicological and nanosafety aspects. - Covers the whole processing route with all aspects of the nanocomposites industry with particular focus on the processing of polymer clay nanocomposites - Includes quality control and nanosafety - Multidisciplinary approach from an industrial perspective
