Self-Adaptive Material Heals Itself, Stays Tough
An adaptive material invented at Rice University combines self-healing and reversible self-stiffening properties.
The Rice material called SAC (for self-adaptive composite) consists of what amounts to sticky, micron-scale rubber balls that form a solid matrix. The researchers made SAC by mixing two polymers and a solvent that evaporates when heated, leaving a porous mass of gooey spheres. When cracked, the matrix quickly heals, over and over. And like a sponge, it returns to its original form after compression.
