Mar 1;() A thermally re-mendable cross-linked polymeric material. Chen X(1), Dam MA, Ono K, Mal A, Shen H, Nutt SR. We have developed a transparent organic polymeric material that can repeatedly mend or “re-mend” itself under mild conditions. The material is a tough solid at.

Another factor, which should cations but close to ideal for others, such as nm and Au 30 nm were deposited onto the affect healing efficiency, is the uniformity self-mending electronic packaging, where surface via electron-beam evaporation.


Values for the original and healed fracture toughness were de- termined by the prop- agation of the starter crack along the mid- dle plane of the spec- imen at the critical load.
