Disclosed are an organic thin film including a semiconducting polymer including a ligand that is metal-coordination bondable or is metal-coordination bonded and an elastomer including a ligand that is metal-coordination bondable or is metal-coordination bonded, wherein the semiconducting polymer and the elastomer are configured to be dynamic intermolecular bonded by a metal-coordination bond, an organic sensor, and an electronic device.

Organic thin film including semiconducting polymer and elastomer configured to be dynamic intermolecular bonded with a metal-coordination bond and organic sensor and electronic device including the same

Various embodiments are directed to apparatuses and methods involving an elastomer material comprising a flexible polymer backbone with a particular ratio of at least first moieties and second moieties. The first moieties provide a first number of dynamic bonds resulting from interactions between the first moieties and the second moieties provide a second number of dynamic bonds resulting from interactions between the second moieties, the second number of dynamic bonds having a weaker bonding strength than the first number of dynamic bonds. The elastomer material, based on the ratio of the first moieties and second moieties, exhibits autonomous self-healing, a particular toughness, and is stretchable.

Stretchable, tough, and self-healing elastomer and applications thereof

A self-healing composite includes a matrix including an elastomer and conductive nanostructures embedded in the matrix, wherein the elastomer includes a polymer main chain, a &#x2014;HN&#x2014;C(&#x2550;O)&#x2014;NH&#x2014; containing first structural unit capable of forming a strong hydrogen bond, and a &#x2014;HN&#x2014;C(&#x2550;O)&#x2014;NH&#x2014; containing second structural unit capable of forming a weak hydrogen bond.

Self-healing composite and device including self-healing film

Various embodiments are directed to a method of forming an apparatus including placing a first electronic circuit in contact with a second electronic circuit, wherein each of the first and second electronic circuits have connector circuits configured and arranged to provide an electrical connection between the first and second electronic circuits and are formed with a polymer film that is configured to adhere, via self-healing, to another polymer film. The method further includes, in response to the contact, causing or facilitating the self-healing of the respective polymer films of the first and second electronic circuits, thereby creating the electrical connection therebetween.
