Analytical investigation of self-heating phenomenon of polymers considering frequency, liquid ageing and molecular-chain motion
The aim of this paper is to present a 1D thermodynamic model describing the rise in temperature induced by self-heating phenomenon occurring in cyclic solicitations of polymers and reinforced thermoplastics. The proposed model was validated for a neat Polyamide 6.6 (PA6.6) for various frequencies and water absorption configurations. This work showed that the presence of water molecules in the network cannot be the only explanation for the observed rise in temperature of the studied aged PA6.6. A physical explanation of this exacerbated rise in temperature is then proposed by modelling the unrecoverable molecular-chain network reorganisation and damage, generally known as the “plasticising” effect of water.
期刊介绍：
Journal of Polymer Research provides a forum for the prompt publication of articles concerning the fundamental and applied research of polymers. Its great feature lies in the diversity of content which it encompasses, drawing together results from all aspects of polymer science and technology.
As polymer research is rapidly growing around the globe, the aim of this journal is to establish itself as a significant information tool not only for the international polymer researchers in academia but also for those working in industry. The scope of the journal covers a wide range of the highly interdisciplinary field of polymer science and technology, including:
polymer synthesis;
polymer reactions;
polymerization kinetics;
polymer physics;
morphology;
structure-property relationships;
polymer analysis and characterization;
physical and mechanical properties;
electrical and optical properties;
polymer processing and rheology;
application of polymers;
supramolecular science of polymers;
polymer composites.
