Book SynopsisIn the last several years, polymer composites have been used heavily in the construction sector, such as to repair or design buildings and bridges, strengthen structures and as stand-alone components. About 30% of all polymers produced each year are used in the civil engineering and building industries. In addition to construction, polymer composites are also used in transportation (moulded parts, fuel and gas tanks), aerospace (satellites and aircraft structures), marine, biomedical (dental fixtures, prosthetic devices), electronics and in recreation industries. Such properties associated with polymer composites, in addition to its performance and applications, are continually being researched. Some topics examined in this book include the durability of the base components of FRP (fiber-reinforced polymer), specifically designed for civil engineering industry. The most common environmental agents, mostly responsible for the deterioration of the materials performance are also discussed. Furthermore, the interfacial adhesion between nanotubes and polymers and the different strategies to promote adhesion are explored to help readers understand the potential and challenges faced by scientists and engineers regarding the use of carbon nanotubes as a reinforcement phase in nanocomposites. This book also reviews the state-of-the-art of syntactic foams and shape memory polymers. The underlying principle for self-heating is also analyzed. Other chapters examine the processing of polymers into antimicrobial materials using polymer/clay nanotechnology, the various methods of synthesis for polyaniline-based nanoparticle-hybrid materials, and the steps towards understanding the complex relationships between specific factors in the production of plastic composites.

Book SynopsisPolymer nanocomposites revolutionised the research in this field owing to the tremendous improvement in the composite properties at very low filler volume fraction. The surface modification of the filler, generally layered silicate montmorillonite clay, is required to compatibilise the organic and inorganic phases. The inorganic clay was modified conventionally with alkyl ammonium ions and the exfoliated nanocomposites with polar polymers could be formed where the clay could be dispersed at nanometer scale. During the initial phase of nanocomposite developments, only ammonium ions of fixed chain length were exchanged on the clay surface. However, this technology suffered when polyolefins and other non-polar polymers were used owing to the difficulties in dispersion of polar clay in the hydrophobic matrices. At best, only partially exfoliated composites could be formed by using these ammonium modified clays. To circumvent these limitations, two possible routes have been followed. By polarising the polymer matrix (e.g. by addition of compatibilisers or surfactants), one can achieve compatibilisation between the organic-inorganic phases. However, this technology leads to deterioration of nanocomposite properties even though better delamination is achieved. On the other hand, one can also focus on the more efficient modification of the filler surface so that the residual polarity after modification of the surface with conventional ammonium ions is also eliminated. A number of new clay surface modification techniques have been developed in the recent years which help in the generation of more exfoliated polymer nanocomposites. These techniques do not rely on the ion exchange of fixed chain length ammonium ions, but lead to generation/exchange of long and polydisperse polymer chains. These techniques include grafting of polymers to the clay surface, grafting of polymers from the clay surface, controlled living polymerisation from the clay surface, in situ generation of polyolefins from the clay surface and clay surface reactions etc. and form very robust technologies for the complete organophilisation of the clay surface. The generation of thick brushes around the clay surface owing to the better surface modification leads to better coverage of the electrostatic forces binding the clay platelets together and also leads to higher basal plane spacing between them. As a result, the modified platelets are more susceptible to exfoliation when compounded with the polymer matrices.

Book SynopsisThis book examines polymer nanocomposites filled by inorganic nanofillers. Polymers are considered as nanocomposite matrix only, possessing, as a rule, an invariable structure. In many respects this situation is explained by the absence of a quantitative structural model of polymers amorphous state. This problem becomes particularly important because all structural elements of polymers have sizes of nanometer scale. The development of notions about polymers amorphous state structure within the frameworks of the cluster model of this structure allows to represent amorphous polymer as a quasitwophase system.

Book Synopsis'A must read for anyone who buys anything plastic' MICHAEL MOSS, PULITZER PRIZE-WINNING AUTHOR OF SALT, SUGAR, FAT Over the past seventy years, McDonald's, Coca-Cola, Procter & Gamble, Unilever and other consumer goods makers have harnessed single-use plastics to turbocharge their profits. They've poured billions of dollars into convincing us we need disposable diapers, cups, bags, bottles, shampoo sachets and ultra-processed foods. We were never clamouring for any of this. But this shift towards disposability has fundamentally transformed our daily habits. Think of toddlers kept in disposable diapers for far longer than their parents wore cloth, our obsession with bottled water and our insatiable appetite for convenient snacks and coffee. While at first we shaped plastics, somewhere along the way, plastics took over and began shaping us. Like any addiction, our plastic habit has consequences. It is damaging our climate and biodiversity - today, the equivalent of one garbage truck of plastic waste ends up in the ocean every minute - and we are only just starting to understand its effect on our own health. In investigating how we got here, Consumed arms us to make better decisions about where we go next. It is only by understanding this history that we will stop accepting the same failed solutions and demand better from the brands that got us hooked on plastic in the first place.
