Flexible Polyurethane (PUR) foams have been used since the 1950s in textiles and furniture upholsteries, and in art and design objects that can now be found in museum collections. Composed from 'short-life' consumer materials, these objects present severe conservation problems as they age. This book presents an in-depth examination of the challenges presented by PUR foams; the case studies of preservation of two works by the artist Piero Gilardi; and a manual on preparing and applying a light stabilizing system that can protect new PUR foams from degrading and restore the flexibility of old foams.

Les répliques de biens de consommation que les artistes zurichois Peter Fischli et David Weiss se sont mis à exécuter dès 1991 oscillent entre une superficialité, dont Fredric Jameson a fait un trait définitoire du postmodernisme, et un épaississement matériel propre aux choses. Ces images d’artefacts, dont on ne peut attendre aucun des services que rendent leurs modèles, nous ramènent pourtant constamment à la lente fréquentation d’objets dans l’usage quotidien qui informe notre vie. S’attachant à examiner la place qu’elles occupent dans l’histoire de l’art contemporain et à décrire notamment la relation qu’elles entretiennent avec les productions artistiques, littéraires, théoriques des années 1960, ce livre est aussi bien une réflexion sur le temps, tel que les œuvres le construisent.

Advances in nanotechnology have boosted the development of more efficient materials, with emerging sectors (electronics, energy, aerospace, etc.) demanding novel materials to fulfill the complex technical requirements of their products. This is the case of polymeric foams, which may display good structural properties alongside functional characteristics through a complex composition and (micro)structure in which a gas phase is combined with rigid ones, mainly based on nanoparticles, dispersed throughout the polymer matrix. In recent years, there has been an important impulse in the development of nanocomposite foams, extending the concept of nanocomposites to the field of cellular materials. This, alongside developments in new advanced foaming technologies which have allowed the generation of foams with micro, sub-micro, and even nanocellular structures, has extended the applications of more traditional foams in terms of weight reduction, damping, and thermal and/or acoustic insulation to novel possibilities, such as electromagnetic interference (EMI) shielding. This Special Issue, which consists of a total of 22 articles, including one review article written by research groups of experts in the field, considers recent research on novel polymer-based foams in all their aspects: design, composition, processing and fabrication, microstructure, characterization and analysis, applications and service behavior, recycling and reuse, etc.

Carbon-based nanomaterials such as carbon nanotubes, graphene and its derivatives, nanodiamond, fullerenes, and other nano-sized carbon allotropes have recently attracted a lot of attention among the scientific community due to their enormous potential for a wide number of applications arising from their large specific surface area, high electrical and thermal conductivity, and good mechanical properties. The combination of carbon nanomaterials with polymers leads to new nanocomposites with improved structural and functional properties due to synergistic effects. In particular, the properties of carbon-based polymer nanocomposites can be easily tuned by carefully controlling the carbon nanomaterial synthesis route and additionally the versatile synergistic interactions amongst the nanomaterials and polymers. This book provides selected examples of the most recent advances regarding carbon nanomaterial-reinforced polymeric composites. It includes the most representative types of polymeric matrices and covers aspects of new processing techniques, novel surface modifications of carbon nanomaterials and their applications in diverse fields, in particular in electronics and energy storage.
