Core-shell nanofibers for developing self-healing materials: Recent progress and future directions

Abstract

The knowledge of self-healing was developed to ensure more durable and reliable engineering materials. Healing agent encapsulation has shown to be one of the most promising approaches in self-healing technology. The healing agents were encapsulated within micro/nanocapsules, micro/nanofibers, and vascular-based networks. Among the methods, using core-shell nanofibers showed a compromising potential for the development of self-healing nanofibers with the minimum drawbacks and limitations. The aim of the present paper is to report the recent contributions on the recent progress of self-healing materials using core-shell nanofibers to provide insights for the further development of self-healing polymeric materials both in academic research and scalable fabrication of polymeric parts in the industries.
