Fig. 4: Electrochemical performance and hemocompatibility of PEDOT: Hep.

a Conductivity, b CV curve at 30 mV s⁻¹, c GCD at 0.5 A g⁻¹; the anticoagulant performance of PEDOT: Hep: d activated partial thromboplastin time (APTT), e prothrombin time (PT), f thrombin time (TT), g fibrinogen content (Fib); and the platelet adhesion SEM of h PEDOT, and i PEDOT: Hep (the yellow circle shows the attached platelets). Data were presented as mean ± SD (n = 3 independent samples) (a, d–g). Statistical analysis by one-way ANOVA with Turkey’s multiple comparisons test (*p < 0.05, **p < 0.01, ***p < 0.001, and ****p < 0.0001 indicate statistical significance) (a, d–g). The similar results are repeated in three independent experiments (h, i).
