Monotonic and cyclic behavior of polyamide 66/hectorite nanocomposites in marine environment:

TL;DR: In this paper, the importance of understanding property degradation due to prolonged exposure of advanced composite materials to simulated environmental conditions is highlighted, which triggers the need for product design for safe performance and operation in harsh environments.

TL;DR: The structure, properties and surface modification of clay minerals, followed by the processing and characterization techniques of polymer nanocomposites and the challenges for the future are discussed in terms of processing, characterization and the mechanisms governing the behaviour of these advanced materials.
Abstract: This paper reviews the recent research and development of clay-based polymer nanocomposites. Clay minerals, due to their unique layered structure, rich intercalation chemistry and availability at low cost, are promising nanoparticle reinforcements for polymers to manufacture low-cost, lightweight and high performance nanocomposites. We introduce briefly the structure, properties and surface modification of clay minerals, followed by the processing and characterization techniques of polymer nanocomposites. The enhanced and novel properties of such nanocomposites are then discussed, including mechanical, thermal, barrier, electrical conductivity, biodegradability among others. In addition, their available commercial and potential applications in automotive, packaging, coating and pigment, electrical materials, and in particular biomedical fields are highlighted. Finally, the challenges for the future are discussed in terms of processing, characterization and the mechanisms governing the behaviour of these advanced materials.

TL;DR: In this article, the influence of the amount of silicate and the absorbed moisture on the mechanical properties of PA6 nanocomposites is discussed, and a more hydrophobic modification of the particles results in a reduction of the degree of exfoliation in PA6, and consequently in a lower modulus, higher ductility and an increased diffusion coefficient compared to particles that are better exfoliated.

TL;DR: The cyclic stress-strain behavior of a wide variety of rigid polymers has been studied as mentioned in this paper, and three classes of fatigue response can be defined, each class displaying a characteristic evolutionary pattern in the stressstrain relation as deformation proceeds from the initial fatigue cycle to fatigue-crack propagation.
Abstract: The cyclic stress-strain behaviour of a wide variety of rigid polymers has been studied Three classes of fatigue response can be defined, each class displaying a characteristic evolutionary pattern in the stress-strain relation as deformation proceeds from the initial fatigue cycle to fatigue-crack propagation Ductile polymers undergo a marked decrease in deformation resistance prior to crack formation; the detailed mechanism by which this “softening” develops can be related to the material microstructure and thermomechanical history Amorphous polymers with a moderate degree of ductility soften slightly; in these materials crazing plays a dominant role in both the cyclic stress-strain response and the structural fatigue resistance Brittle and nearly-brittle polymers are essentially stable in cyclic deformation; the fatigue resistance of these materials is very sensitive to strain amplitude in cyclic deformation
