Cyclodextrin based intelligent materials have been known for quite a few years. These substances possess unique characterististics that can be used for self-healing of materials like car paints, plates or covers for e.g. mobile devices. Sumitomo Chemical company, among others has a patent application (US2018215837 (A1)) for Resin and surface protective plate or automotive material. In the product, rotaxanes, lace-like derivatives of cyclodextrins are mentioned.
What do you think? Is this indeed a new area for intelligent and self-healing materials with real commercial interest or just some fascinating science?
