for 3 h, the film recovered to its original shape, and the wound on both sides touched
each other, and then the crack was healed due to the reformation of
β-CD-Ad. Moisture or water has the advantages of being green, inexpensive, and
moderate. This athermal triggered shape memory-assisted self-healing ability shows
great values for biomedical and biotechnology applications.
22.5 Prospect
In this chapter, we have highlighted a burgeoning trend in SMPs and SHPs design
than exploits CDs-based interactions to endow shape memory or self-healing function to the materials. The nature of host-guest interactions not only always determines the triggering method of SMPs and SHPs but also provides some other
functions to the materials. The development of new trigger methods and new
functionalities is desirable for broadening SMPs and SHPs applications to new
territories. But several challenges still exist. For example, SMPs and SHPs based
on CD-guest interactions always have relatively poor mechanical strength compared
with the conventional SMPs and SHPs, since the strength of CD-guest interactions is
weaker than that of chemical bonds. It is a big challenge to increase the mechanical
properties of SMPs and SHPs based on CD-guest interactions to meet the requirements of applications. In addition, simplify their fabrication for realistic applications
is also a challenge that requires attention.
