a Sample 7-day shrinkage tests and results under the condition of constant temperature and humidity for PVPEM, PEM1.5, HEM1.5, KEM1.5, KEM2.0 and KEM2.4, respectively. Scale bar, 1 cm. b Photographs of the KEM1.5, ClG and CoG samples for the permeability and application on the skin. c Photographs from the in vitro blood-clotting measurement and the corresponding relative OD values of the supernatant absorbance for PVPEM (n = 9), HEM1.5 (n = 9), PEM1.5 (n = 9), KEM1.5 (n = 9), KEM2.0 (n = 9), KEM2.4 (n = 9), ClG (n = 9), CoG (n = 9), respectively. Data were expressed as mean ± s.d.; \(^{\ast\ast\ast\ast}\), p < 0.0001. Student’s t test (two-sided) was used for statistical analysis of between two groups comparison in (c). d The SEM images of blood cells on the KEM1.5 surface. Data were analyzed from at least three independently experiments in (d). e Illustration of blood components permeation and contact to the KEM1.5. All experiments were replicated at least three times independently with similar results. Source data are provided as a Source Data file.
