Abstract:
1. A self-healing polymer material comprising a primary polymer phase and a secondary polymer phase, wherein: the primary polymer phase comprises a thermoset polymer matrix; the secondary polymer phase comprises a thermoplastic polymer that is provided in the primary polymer phase as a dispersion of discrete portions in the form of particles and/or fibres that are capable of acting as a self-healing agent and are chemically reactive on post-curing or healing of the self-healing polymer material; the thermoplastic polymer is capable of flowing in the thermoset polymer matrix on post-curing or healing of the self-healing polymer material, and includes functional groups attached to and/or incorporated into a backbone of the polymer, the functional groups of the thermoplastic polymer being capable of chemical bonding or reaction with functional groups of the thermoset polymer matrix on post-curing or healing of the self-healing polymer material; and the functional groups attached to and/or incorporated into the backbone of the thermoplastic polymer are capable of forming a volatile by-product on chemical reaction with functional groups of the thermoset polymer matrix, on post-curing or healing of the self-healing polymer material.
