Special Issue Information

Dear Colleagues,

Summary: Nature-inspired self-healing strategies have been explored in biomimetic engineering designs, with the aim of restoring structural damage. In addition to cracks on aircraft fuselage and nuclear power plant walls, numerous structures require protection as human activities expand, including areas such as submarine tunnels and spacecraft. In recent years, successful efforts have been made to develop and test a variety of self-healing materials, which are the focus of the current Special Issue. Here, we discuss cutting-edge technologies in such materials and existing healing methods; additionally, we include physical and chemical approaches to constructing self-healing polymers, such as diffusion and flow, shape memory effects, covalent bond reformation and reshuffling, supramolecular chemistry, and heterogeneous systems. We highlight the advantages and challenges of different types of self-healing polymers, such as hydrogen-bonded, metal-coordinated, and ionic as well as dynamic covalent polymers. We showcase some of the promising applications of self-healing polymers in energy, optoelectronics, biomedicine, and aerospace engineering. This Special Issue highlights the advances in and applications of novel self-healing on structural materials and their composites. We also welcome in-depth and comprehensive studies on the physicochemical and mechanical foundations associated with this field.

This research work studies the self-healing ability, mechanical properties, and shape memory of the polymer Surlyn® 8940 with and without multiwall carbon nanotubes (MWCNTs) as a nanoreinforcement. This polymer comes from a partially neutralized poly(ethylene-co-methacrylic acid) (EMAA) ionomer copolymer. MWCNTs and the polymer went through a mixing process aimed at achieving an excellent dispersion. Later, an optimized extrusion method was used to produce a uniform reinforced filament, which was the input for the 3D-printing process that was used to create the final test samples. Various concentrations of MWCNTs (0.0, 0.1, 0.5, and 1.0 wt.%) were used to evaluate and compare the mechanical properties, self-healing ability, and shape memory of unreinforced and nanoreinforced materials. Results show an enhancement of the mechanical properties and self-healing ability through the addition of MWCNTs to the matrix of polymer, and the specimens showed shape memory events. Full article
