ABSTRACT

This review outlines latest developments in the field of self-healing rubbers and elastomers, analyzing their potential application to natural rubber (NR). Different validated healing concepts are presented and the possibilities of applying them to NR are discussed. Research in this field should aim at modifying the chemical structure of NR as to enhance physical or chemical reversible interactions either intermolecular or intramolecular. The realization of better mechanical properties at relevant working conditions and with milder healing conditions remains a challenge for all self-healing rubbers. This overview should be seen as setting the conceptual framework for new developments with a more clearly defined industrial focus.
