According to the Korean Research Institute of Chemical Technology and the National University of Puken, a joint research group has developed a self-healing material that has no analogues in the world in terms of mechanical strength. Damage repair occurs at room temperature.

According to the members of the research team, the new material benefits from increased hardness and strength from existing self-healing polymer materials that have been developed for use in clothing, shoes, tires, folding displays and other products.

To ensure the ability to recover independently, the material must have relatively weak intermolecular bonds, but this negatively affects such an indicator as the tensile strength.

In the material that we have developed, the degree of molecular bonds increases instantly in the event of external friction or impact, and then there is a recovery with a return to a state of free molecular motion, " the scientists explain. - The ultimate tensile strength is at least 43 MPa, which is close to a polyurethane shoe sole, whereas the previous value was 30 MPa.

In addition, the strength of the material depends on the degree of external influence. In other words, the greater the force applied, the stronger the material resists possible damage.
