Special Issue Information

Dear Colleagues,

For decades, the study of correlations between mechanical stresses and deformation in polymeric materials, whether in a solid or molten state, has been a thriving research and development area. It is easy to understand this interest when we translate these correlations into practical terms regarding the processing, structural characterization, and end-use of these materials. More specifically, the study of polymers' rheological properties, especially in the molten state, finds a series of practical and theoretical applications, from the morphological and structural investigation of pure polymers and compounds to processing computational simulations, among others. On the other hand, the investigation of mechanical properties in solid polymers, both in the short and long term, is essential for developing new polymeric systems for use in engineering projects. This includes failure prediction, creep behavior, stress relaxation, fatigue, and fracture mechanisms.

Innovative characterization techniques and data interpretation, theoretical study, and computer simulation have kept these topics in rapid development over the last few years.

This Special Issue, entitled Polymer Physical Properties: Viscoelasticity, Rheology, and Mechanical Properties, is devoted to the latest advances in research and development in this field. Both original contributions and comprehensive reviews are welcome. 

Areas of interest include:

  • Physicochemical properties vs. rheology
  • Correlations between rheological properties and morphology and structure
  • Application of rheology in composites and nanocomposites
  • Elasticity and viscoelasticity
  • Rheometry
  • Mechanical testing
  • Long-term mechanical properties
  • Polymer processing simulation
  • Fracture mechanisms
  • Fatigue
  • Mathematical modeling
  • Theory and simulation of mechanical and rheological properties.

Abstract
Using a split-Hopkinson pressure bar test instrument with a temperature control device, in this work, silicone rubber was tested at different temperatures (−40 °C–200 °C) and different strain rates (1.2 × 103 s−1–7.2 × 103 s−1). The [...] Read more.
Using a split-Hopkinson pressure bar test instrument with a temperature control device, in this work, silicone rubber was tested at different temperatures (−40 °C–200 °C) and different strain rates (1.2 × 103 s−1–7.2 × 103 s−1). The results showed that the dynamic mechanical properties of silicone rubber were strain-rate sensitive at different temperatures and the yield strength of the silicone rubber increased with an increase in the strain rate. At a higher strain rate, silicone rubber showed temperature sensitivity. With a decrease in the strain rate, the influence of temperature on silicone rubber gradually decreased. Differential scanning calorimetry analysis showed that silicone rubber had good thermal stability at high temperatures. When the temperature was as low as −40 °C, the silicone rubber underwent a glass transition, showing the characteristics of brittle materials. Full article
