(a) A schematic illustration of the tape-peeling tests for DENS w/F-SAM, performed using a sticky tape; (b) SEM images showing the changes in the morphology of DENS with F-SAM and the commercially available particle-based coating (PBC) after 10, 20, 30 tape-peel test cycles (scale bars: 20 and 200 μm for DENS w/F-SAM and PBC, respectively); (c) changes in the CA and CAH according to repeated tape-peeling tests; (d) a schematic illustration of the linear abrasion tests for LIDENS; (e) representative AFM images showing the morphologies of LIDENS after 10, 20, 30 cycles of linear abrasion tests; (f) changes in the CA and CAH according to repeated linear abrasion tests; (g) measured SA for LIDENS during repeated sterile autoclave cycles and lubrication process; (h) reversible CA during the repeated autoclave and lubrication process.
