<jats:p>We suggest a thermally curable, “sticky” nano‐adhesive for future flexible display applications. Due to the low glass transition temperature (T<jats:sub>g</jats:sub>), nano‐adhesive is readily attachable to various substrates. The adhesive was thermos‐curable via an ionic cross‐linking reaction within 5 min at 120 °C. The thickness of the nano‐adhesive can be reduced down to 50 nm and formed a uniform, conformal adhesion in a large area.</jats:p>
