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.
