The plateau modulus (G N 0) of the PU adhesive was defined as the storage modulus at the angular frequency where the loss tangent was minimum (Fig. 2 b and S3) [36].PU adhesives possess cross-linked bonds that form a network structure, resulting in a plateau region. However, the plateau region of the PU adhesive exhibits a
