Graphical Abstract


This presentation will highlight some recent advances in multifunctional composite interphases. Our approach based on hierarchical structures of micro- and nanofillers in polymer matrix composites is proposed to develop stimulus-response ability. 2D nanofillers are used to integrate mechanical, optical and electrical functionalities into conventional fibre surfaces and polymer matrix composite interphases, which are transition regions where the chemical, mechanical and physical properties change from the bulk properties of reinforcement to the bulk properties of the polymer matrix. The nanofiller-rich interphases are able to detect and make utility of microcracks as real-time in-situ sensors for early warning catastrophic failure of materials. The stimulus-response composite interphases will enable various designs for many ‘smart’ applications for pipeline industry, which also will bring new opportunities to wide range of composite materials.
