Self-healing of polymers has drastically developed in the last decade, and in some cases, applications are already used in the industry. Despite the large number of solved problems, some of them remain. One of them is the principle of self-healing based on chain mobility, which works well in the case of thermoplasts, while lower in thermosets. The study presents the modification of thermoset epoxy/amine system with Diels-Alder components (furan, maleimide) for the purpose of self-healing.

COBISS.SI-ID: 1537460931One of the more useful principles for self-healing polymeric materials is based on chain mobility. The study presents the potential modification of the polymer network with smaller molecular fragments, which successfully contribute to the self-healing of the entire material. One of the aspects of the study is to evaluate the potential of furan/maleimide chemistry for the functionalization of epoxy materials, thus causing the effect of self-healing based on the bifunctional healing mechanism, chain mobility of the partially crosslinked structure and furan/maleimide-based DA reaction chemistry.

COBISS.SI-ID: 1536818883It is known that maleimide functionalized benzoxazines have high glass transition temperatures (200 to 350 °C) and good thermal stability. Due to these characteristics, these systems have great potential as high-performance materials. This work describes a new approach to the synthesis of maleimidobenzoxazines and for the first time offers the possibility of phenolic diversity in the final molecule of maleimidobenzoxazines.
