Die Dissertation legt die Überwindung der Nachteile von niedrig gefüllten Nanopartikel–Polymer–Kompositen durch die anfängliche Herstellung eines stabilen, perkolierenden anorganischen Nanopartikelgerüsts dar. Dessen sehr hohe Porosität wird entweder aus der Gasphase mittels Flammensprühpyrolyse (FSP) oder alternativ über nasschemische Präparation mittels Sol–Gel–Verfahren erreicht. Im Anschluss werden die perkolierenden Strukturen mittels kapillargetriebener Infiltration mit einem Monomer gefüllt, welches daraufhin photochemisch polymerisiert wird. Das erhaltene System wird inverses Nanopartikel–Polymer–Komposit genannt. Dünne Schichten daraus können beispielweise für haftvermittelnde, elektrische sowie optoelektronische Funktionsmaterialien eingesetzt werden. Die ursprüngliche Partikelnetzwerk– und Porenstruktur bleibt während der Präparation erhalten und durch die Infiltration sowie anschließende Monomer–Polymerisation konnte die elektrische Leitfähigkeit von Halbleiternanopartikeln deutlich gesteigert werden. Für den Reaktionsmechanismus innerhalb der mesoskaligen Porenstruktur wurde ein analytisches Kinetikmodell der freien radikalischen Photopolymerisation unter Einschluss entwickelt und mit diffuser Reflexions-FTIR-Spektroskopie (DRIFTS) bestätigt.

Clay–Polymer Nanocomposites is a complete summary of the existing knowledge on this topic, from the basic concepts of synthesis and design to their applications in timely topics such as high-performance composites, environment, and energy issues. This book covers many aspects of synthesis such as in- situ polymerization within the interlamellar spacing of the clays or by reaction of pristine or pre-modified clays with reactive polymers and prepolymers. Indeed, nanocomposites can be prepared at industrial scale by melt mixing. Regardless the synthesis method, much is said in this book about the importance of theclay pre-modification step, which is demonstrated to be effective, on many occasions, in obtaining exfoliated nanocomposites. Clay–Polymer Nanocomposites reports the background to numerous characterization methods including solid state NMR, neutron scattering, diffraction and vibrational techniques as well as surface analytical methods, namely XPS, inverse gas chromatography and nitrogen adsorption to probe surface composition, wetting and textural/structural properties. Although not described in dedicated chapters, numerous X-ray diffraction patterns of clay–polymer nanocomposites and reference materials are displayed to account for the effects of intercalation and exfoliations of layered aluminosilicates. Finally, multiscale molecular simulation protocols are presenting for predicting morphologies and properties of nanostructured polymer systems with industrial relevance. As far as applications are concerned, Clay–Polymer Nanocomposites examines structural composites such as clay–epoxy and clay–biopolymers, the use of clay–polymer nanocomposites as reactive nanocomposite fillers, catalytic clay-(conductive) polymers and similar nanocomposites for the uptake of hazardous compounds or for controlled drug release, antibacterial applications, energy storage, and more. - The most comprehensive coverage of the state of the art in clay–polymer nanocomposites, from synthesis and design to opportunities and applications - Covers the various methods of characterization of clay–polymer nanocomposites - including spectroscopy, thermal analyses, and X-ray diffraction - Includes a discussion of a range of application areas, including biomedicine, energy storage, biofouling resistance, and more

This book, consisting of 21 articles, including three review papers, written by research groups of experts in the field, considers recent research on reinforced polymer composites. Most of them relate to the fiber-reinforced polymer composites, which are a real hot topic in the field. Depending on the reinforcing fiber nature, such composites are divided into synthetic and natural fiber-reinforced ones. Synthetic fibers, such as carbon, glass, or basalt, provide more stiffness, while natural fibers, such as jute, flax, bamboo, kenaf, and others, are inexpensive and biodegradable, making them environmentally friendly. To acquire the benefits of design flexibility and recycling possibilities, natural reinforcers can be hybridized with small amounts of synthetic fibers to make them more desirable for technical applications. Elaborated composites have great potential as structural materials in automotive, marine and aerospace application, as fire resistant concrete, in bridge systems, as mechanical gear pair, as biomedical materials for dentistry and orthopedic application and tissue engineering, as well as functional materials such as proton-exchange membranes, biodegradable superabsorbent resins and polymer electrolytes.
