Fig. 1: Design and characterization of asymmetric Janus adhesive tape.

From: Asymmetric Janus adhesive tape prepared by interfacial hydrosilylation for wet/dry amphibious adhesion

Fig. 1

a Schematic of Janus adhesive tape with an asymmetrically crosslinked network prepared through an interfacial hydrosilylation strategy. The lightly crosslinked PDMS acts as an adhesive layer with high adhesion, and the highly crosslinked PDMS acts as a supporting layer with high mechanical strength. b Visible spectra at the interfacial transitional region of the Janus adhesive tape. The gradual increase in the absorption peak at 518 nm (probed by Oil Red) indicates the gradient diffusion of the curing agent across the interface. Note that the supporting layer (20:1) was kept transparent and that the adhesive layer (50:1) was dyed with Oil Red. c The mechanical and d adhesion properties of the Janus adhesive tape, with HCPDMS tape and LCPDMS tape used as controls. e The Janus PDMS tape shows apparent asymmetric adhesion performance of its two sides and can withstand large deformations
