Melanin, a natural biopolymer with conjugated backbone, stands out as promising candidate for bioelectronics owing to its redox activity, metal ion chelation, hydration-dependent electrical response, wet adhesion, potential electronic transport, anti-inflammatory properties, and excellent thermal stability. In this study, we explore the impact of hybridizing liquid crystalline graphene oxide (LCGO) into conductive melanin-like polymer polydopamine (PDA) on morphology, stability, synergistic electrochemical performance. Our findings reveal that gold electrode coated PDA:LCGO composites exhibit more than two orders magnitude lower impedance 100 times higher charge storage capacity compared both bare electrodes those pure PDA. Furthermore, demonstrate morphology performance could be tuned by adjusting synthesis parameters in deposition. This composite, superior performance, holds promise diverse applications ranging from biosensors implantable bionic interfaces.
