Figure 4

The dual‐properties of wet bioadhesion and slipperiness of the hybrid patch. a) The schematic diagram showing the dual‐properties of the hybrid patch. b–d) The peeling curves of the hybrid patch after adhering on the porcine, stomach and intestine for 0, 6, 12, 24, and 72 h, respectively. e–g) The interfacial toughness of the hybrid patch after adhering on the porcine, stomach, and intestine for 0, 6, 12, and 24 h, respectively (n = 3, biologically independent samples). Data are showed as mean ± SD. h) The contact angles of the water droplet on the PLGA scaffold, PLGA inverse opal scaffold, and hybrid patch infused with paraffin oil. i) Images showing the water droplet keeping still on the PLGA inverse opal scaffold with the surface rotating from 0° to 60°. j) Images showing the sliding process of the water droplet on the slippery surface of the hybrid patch with the sliding angels of 6°.
