Download or read book Sustainable Food Packaging Technology written by Athanassia Athanassiou and published by John Wiley & Sons. This book was released on 2021-05-10 with total page 464 pages. Available in PDF, EPUB and Kindle. Book excerpt: Towards more sustainable packaging with biodegradable materials! The combination of the continuously increasing food packaging waste with the non-biodegradable nature of the plastic materials that have a big slice of the packaging market makes it necessary to move towards sustainable packaging for the benefit of the environment and human health. Sustainable packaging is the type of packaging that can provide to food the necessary protection conditions, but at the same type is biodegradable and can be disposed as organic waste to the landfills in order to biodegrade through a natural procedure. In this way, sustainable packaging becomes part of the circular economy. ?Sustainable Food Packaging Technology? deals with packaging solutions that use engineered biopolymers or biocomposites that have suitable physicochemical properties for food contact and protection and originate both from renewable or non-renewable resources, but in both cases are compostable or edible. Modified paper and cardboard with increased protective properties towards food while keeping their compostability are presented as well. The book also covers natural components that can make the packaging functional, e.g., by providing active protection to the food indicating food spoilage. * Addresses urgent problems: food packaging creates a lot of hard-to-recycle waste - this book puts forward more sustainable solutions using biodegradable materials * State-of-the-art: ?Sustainable Food Packaging Technology? provides knowledge on new developments in functional packaging * From lab to large-scale applications: expert authors report on the technology aspects of sustainable packaging

Download or read book Natural Polymers and Biopolymers II written by Sylvain Caillol and published by MDPI. This book was released on 2021-05-05 with total page 472 pages. Available in PDF, EPUB and Kindle. Book excerpt: BioPolymers could be either natural polymers – polymer naturally occurring in Nature, such as cellulose or starch…, or biobased polymers that are artificially synthesized from natural resources. Since the late 1990s, the polymer industry has faced two serious problems: global warming and anticipation of limitation to the access to fossil resources. One solution consists in the use of sustainable resources instead of fossil-based resources. Hence, biomass feedstocks are a promising resource and biopolymers are one of the most dynamic polymer area. Additionally, biodegradability is a special functionality conferred to a material, bio-based or not. Very recently, facing the awareness of the volumes of plastic wastes, biodegradable polymers are gaining increasing attention from the market and industrial community. This special issue of Molecules deals with the current scientific and industrial challenges of Natural and Biobased Polymers, through the access of new biobased monomers, improved thermo-mechanical properties, and by substitution of harmful substances. This themed issue can be considered as collection of highlights within the field of Natural Polymers and Biobased Polymers which clearly demonstrate the increased interest in this field. We hope that this will inspire researchers to further develop this area and thus contribute to futures more sustainable society.”

Download or read book Nature inspired Polymers written by Jesse Thomas Ernest Quinn and published by . This book was released on 2018 with total page 157 pages. Available in PDF, EPUB and Kindle. Book excerpt: The concept of an organic thin film transistor was first introduced in the late 1980s and research was directed toward two key merits of performance, field-effect mobility and current ON/OFF ratio. Today these two key merits of performance are still highly sought after; however, a shortcoming associated with most organic semiconductors is their susceptibility to chemical interactions and photo-excitation; to name but a few of their caveats. Consequently, the development of organic semiconductors with high charge carrier transport as well as good air stability is still desired. Nature provides a vast diversity of materials and looking for natural or nature inspired semiconductors appears to be a promising route towards interesting and pertinent materials. Organic thin film transistors based on natural or natural-inspired semiconductors such as indigo, -carotene, indanthrene, and perylene diimide have demonstrated good charge carrier transport and some cases demonstrated equally good stability in ambient conditions. In this work, a number of moderately to excellent air stable polymeric semiconductors were designed and synthesized that were nature inspired. Chapter 3 describes the synthetic account and elaborates on a broad spectrum of properties pertaining to the novel fluorene-fused triphenodioxazine based polymer (PFTPDOBT). PFTPDOBT exhibited excellent charge transport performance in ambient conditions reaching hole mobilities as high as ~10^-2 cm^2 V^-1 s^-1 and modest hole mobilities in water-gated transistors (~10^-3 cm^2 V^-1 s^-1). In Chapter 4, a series of pyrazino[2,3-g]quinoxaline-2,7-dione (PQx) based polymers were developed and characterized. These PQx based polymers displayed exciting UV-Vis-NIR spectra when in the presence of an organic acid or Lewis acid. Their electrical characteristics in OTFTs were typical of ambipolar charge transport. Hole mobilities reached as high as ~10^-2 cm^2 V^-1 s^-1 with corresponding electron mobilities as high as ~10^-3 cm^2 V^-1 s^-1. Lastly, Chapter 5 gives accounts on significant research pertaining to novel polymeric semiconductors based on the pyrimido[4,5-g]quinazoline-4,9-dione (PQ) moiety. A systematic study of PQ-based polymeric semiconductors is presented in both nitrogen, ambient, and aqueous environments. Typical hole charge transport was obtained between ~10^-2 and ~10^-3 cm^2 V^-1 s^-1. Both PPQ2T-BT-24 and PPQ2T-TT-24 demonstrated moderate to excellent stability in these environments. To exploit the photo-excitation of organic semiconductors, a series of PQ-based polymeric semiconductors were incorporated in phototransistors and also blended with PC61BM. The PPQ2T-BT-24:PC61BM blend reached ultrafast response times as low as 1 ms for rise and 8 ms for fall with photoresponsivity as high as 0.88% and EQE of 189%. Lastly, PPQ2T-BT-24 and PPQ2T-TT-24 were incorporated into OTFT gas sensors where they demonstrated low detection limits with fast recovery times for a particular analyte.
