The present invention provides a joined body with no risk of detachment from the joining surface without using an adhesive, and a method for producing the joined body. The present invention also provides a reversible joined body that enables control of joining and dissociation, and a method for producing the reversible joined body. In the joined body, a chemical bond is formed between two or more same or different solid-state materials at their contact interfaces by a chemical reaction.
A self-healing thermal interface material includes a reactive silicone-based material and a thermally conductive filler material. The reactive silicone-based material is modified to include one or more hydrogen bonding functional groups.

The crystal structures of 9-(4-vinylbenzyl)adenine, C14H13N5, and 1-(4-vinylbenzyl)uracil, C13H12N2O2, are composed of zigzag ribbon-like structures that are stabilized by conventional (N-H...N-type) hydrogen bonds for the former and conventional (N-H...-type) and non-conventional (C- H...O-type) hydrogen bonds for the latter; the hydrogen-onding patterns are represented by graph-sets R-2(2) (9) and R-2(2) (8), respectively. The adenine and uracil moieties in these alkylated derivatives are planar and are inclined at angles of 84.44 (4) and 79.07 (7)degrees, respectively, with respect to the phenyl rings.
