Przemysł opakowań to obecnie jeden z najprężniej rozwijających się sektorów gospodarki światowej. Rosnące wymagania stawiane współczesnym opakowaniom wpływają na zmiany ich form konstrukcyjnych i stosowanie materiałów o specyficznych parametrach, np. wysokiej barierowości, odporności termicznej i mechanicznej, co stwarza przestrzeń do rozwoju innowacji opakowaniowych. W ten nurt wpisuje się prezentowana monografia. Celem głównym podjętych studiów literaturowych i badań empirycznych było scharakteryzowanie organiczno-nieorganicznych materiałów hybrydowych, a także opracowanie metod syntezy nowych hybryd na bazie żelatyny i związków krzemoorganicznych. Szczególny nacisk położono na określenie możliwości zastosowania opracowanych układów hybrydowych jako potencjalnych materiałów opakowaniowych.

Nanopapers: From Nanochemistry and Nanomanufacturing to Advanced Applications gives a comprehensive overview of the emerging technology of nanopapers. Exploring the latest developments on nanopapers in nanomaterials chemistry and nanomanufacturing technologies, this book outlines the unique properties of nanopapers and their advanced applications. Nanopapers are thin sheets or films made of nanomaterials such as carbon nanotubes, carbon nanofibers, nanoclays, cellulose nanofibrils, and graphene nanoplatelets. Noticeably, nanopapers allow highly concentrated nanoparticles to be tightly packed in a thin film to reach unique properties such as very high electrical and thermal conductivities, very low diffusivity, and strong corrosion resistance that are shared by conventional polymer nanocomposites. This book presents a concise introduction to nanopapers, covering concepts, terminology and applications. It outlines both current applications and future possibilities, and will be of great use to nanochemistry and nanomanufacturing researchers and engineers who want to learn more about how nanopapers can be applied.

In recent years, advanced nanocomposites have attracted a great deal of attention from materials engineers and industrialists due to numerous advantages, including the use of a small amount of nanofillers to significantly enhance the material properties of resulting nanocomposites, widespread applications in a range of fields, such as automobiles, aerospace and aerocrafts, building structures, biomedical devices, et cetera, as well as easy processibility based on current manufacturing technologies, such as melt compounding, solution casting, in situ polymerisation and electrospinning. Advanced nanocomposites reinforced with carbon nanotubes (CNTs), graphene oxides (GOs), nanoclays, nanocellulose, and nanofibres demonstrate excellent multifunctional properties, consisting of better mechanical, thermal, electrical, and barrier properties. The key issue is still the encountered challenge of homogeneous filler dispersion in morphological structures for tailored advanced nanocomposites. Hence, processing-structure-property nanocomposite relationship is crucial for their future development as innovative hybrid material systems. This Special Issue will address above-mentioned points in relation to manufacturing, characterisation, and properties of advanced nanocomposites to offer an insight into this new composite family with the incorporation of nanofillers, nanoparticles, and nanomaterials in order to eventually achieve the nanotechnological "bottom-up" scheme.

The book, Nanorods and Nanocomposites aims to provide the reader with an overview of the recent advances made on the synthesis of nanorods and nanocomposites and their emerging applications for a better lifestyle. The nanorods are a surprising gift to materials science from the research field of nanoscale materials. Nanorods promise to serve as a building block of the next-generation electronic and optoelectronic devices. Nanocomposite materials are multiphase solid materials that have one organic or inorganic nanoarchitectured compound with various nanostructures, such as nanoparticles, nanowires, nanorods, and nano-films, etc., or with multiphase solid materials (metals, oxides, polymers, and carbon). Due to the progressive physical, chemical, electrical, thermal, optical, electrochemical, and catalytic properties of nanocomposites, they exhibit multi-functional characteristics in a variety of engineering applications such as piezoelectrics, thermoresistors, sensors, energy-related technologies, water purification catalysts, electro-photonics, and so on. Despite the wide variety of applications due to their unique nanostructures, the fabrication of nanocomposites and the realization of their applications in different fields remains a challenging task. The focus of this book is to provide a platform for presentation of the latest knowledge and recent progress in synthesis, functionalization, and applications of nanocomposite materials. It is expected that this book presents the most attractive and versatile technological developments in the field of nanorods and nanocomposite materials and their applications that will provide a better understanding of the currently ongoing research in related fields.

This Special Issue focuses on ferrite-based nanomaterial synthesis and characterization including (i) Synthesis, (ii) Advanced chemical and physical characterization of structure and properties, (iii) Magnetic behaviour, (iv) Computational and theoretical studies of reaction mechanisms, kinetics, and thermodynamics, (v) Applications of nanomaterials in environmental, biological, catalytic, medical, cultural heritage, food, geochemical, polymer, and materials science. Additionally, the effect of reaction time, reaction temperature, and oleic acid concentration on the properties of CoFe2O4 nanoparticles was investigated. In this Special Issue, the effect of SiO2 embedding on the production of single-phase ferrites, as well as on the structure, morphology and magnetic properties of (Zn0.6Mn0.4Fe2O4)δ(SiO2)100-δ (δ = 0-100%) NPs, synthesized by the sol-gel method and annealed at different temperatures, is analysed. The obtained results indicated that the preparation route strongly influences the particle sizes and, implicitly, the magnetic behaviour of the NPs. The Zn0.6Mn0.4Fe2O4 embedded in SiO2 exhibits superparamagnetic-like behaviour, whereas the unembedded Zn0.6Mn0.4Fe2O4 behaves similar to a high-quality ferrimagnet. This Special Issue also includes the study on Bi2Cu(C2O4)4·0.25H2O synthesis by thermolysis, followed by its integration within a CuBi/carbon nanofiber (CNF) paste electrode and its application in electrochemical detection of amoxicillin (AMX) in aqueous solution. By adding a concentration step in the detection protocol, selective and simultaneous detection of AMX in a multi-component matrix is also possible.

In the last decades, nanoscience and nanotechnologies have offered new opportunities for producing materials with structural and functional properties. The possibility to manipulate the matter, on an atomic or molecular level, can allow the obtainment of structures having unique characteristics and completely new functionalities. The use of structural and functional nanoparticles to be added to polymer nanocomposites is a nice way to manipulate the matter's properties following a bottom-up approach. The hybrid fillers can be used, not only as for structural purposes, but also as functional nano-structures in many fields, such as microelectronics, packaging, drug delivery, flame retardant materials, and environmental issues. A number of interesting nanoparticles, such as clays (lamellar or tubular), silica, carbon nanotubes, siloxanes, and, more recently, graphenes, have emerged as peculiar nanofillers for enhancing the performance of polymer matrices for a wide variety of technological applications. The present chapter aims to present the last research and novelty in the field of polymeric nanocomposites' materials. Methods of productions, as well as polymers and type and shape of the fillers and their functionalities are widely reported. Structural organization and physical properties of the polymer matrix are correlated with the nature of filler.
