Over the past few decades, there has been a growing interest in materials that can self-heal as they may have longer lifetimes and lower production costs. Driven the design of a supramolecular healable materials, many elegant and creative methods have been suggested such as ionic interactions, chemo-mechanical self-healing, covalent bonding, and shape memory polymers. In this study, we describe new stagey for healable materials based on poly(ethylene oxide) (PEO) nanocomposite using chain diffusion by water molecules. As a healing material, organic/inorganic nanocomposite composed with PEO and halloysite is prepared by 60Co r-ray irradiation. This material has the ability repair itself following damage due to segment mobility by addition of water. Two broken species are attached each other by physical approach having water molecules, the fractured surfaces become intermixed through chain diffusion and tangled. It is meaningful work using intact PEO character for self-healing materials. |
