Self-healing adhesives Researchers at Oak Ridge National Laboratory (Oak Ridge, Tenn.; www.ornl.gov) developed a series of autonomous self-healable and highly adhesive elastomers that are fabricated via a simple, efficient and scalable process. The self-healing elastomers demonstrated unprecedented adhesion strength and the ability to adhere to many surfaces, which could broaden their potential use in industrial applications. In a recent study published in Advanced Functional Materials, ORNL researchers used a blend of a self-healing polymer with curable elastomers to produce a series of self-healable and highly adhesive materials. The team proved that these elastomers can self-repair in ambient temperatures and conditions, as well as underwater, with their adhesive force only minimally impacted by surface dust. “These tough elastomers can be made simply and efficiently through a scalable process, enabling a wider range of uses for the building, automotive and electronics industries,” ORNL’s Diana Hun says.
