Description
The increasing environmental awareness of the society is the main driving force for holistic sustainability considerations in the production and design of materials designated as ecodesign. The continuous development of polymers meets the challenges of the industrial demands and the increasing social focus on ecological awareness. One innovation represents the comparative recent developed polymer class based on covalent adapted networks (CAN). These combine the properties of thermoplastics and thermosets, which resulting in multiple malleable thermoset like materials. With regard to ecodesign these polymer systems meet many of the concepts requirements and therefore own a great potential to replace thermosets and its composites in structural and functional applications. The most important issues of Ecodesign are durability, including the reparability, and the recycling.
In contrast to commercial thermosets and thermoplastics (CAN)- based polymers are suitable for a sustainable product design and the product lifetime extension. The current state of research mainly focus the synthesis options and there is still a lack of knowledge about technical relevant properties.
The aim of this work is to characterize the durability and mechanical properties of this polymer class, focussing the alternating loading and the self-healing properties. The investigation of the creep and relaxations behavior is also considered. For this purpose, among others, a recyclable vinylogous urea vitrimer is used as an example.
The presented studies will give insight into the mechanical properties in terms of durability and the service life and evaluate the engineering relevance and the potential of ecodsign of CAN-based polymers. These findings will enable the assessment of new areas of application for this class of polymers. This research was funded by Bundesministerium für Bildung und Forschung, grant number 03XP0001.
