Background:

• Graphene/metal nanocomposites are crucial for electronic applications.
• Silver nanowires (AgNWs) combined with graphene derivatives enhance composite conductivity.
• Developing efficient conductive networks is key for advanced electronics.

Purpose of the Study:

• To create highly conductive hydrophilic hybrids of functionalized and reduced graphene oxide (f-rGO) and AgNWs.
• To investigate two synthesis routes: physical mixture and in situ reduction.
• To evaluate the role of AgNWs in improving graphene derivative electrical properties.

Main Methods:

• Synthesized f-rGO/AgNWs composites via physical mixing and in situ reduction.
• Incorporated AgNWs into few-layered graphene/functionalized multiwalled carbon nanotube hybrids.
• Prepared gravure printing inks from f-rGO/AgNWs composites for rheological and printing tests.

Main Results:

• Composites demonstrated significant improvements in electrical conductivity due to synergistic effects.
• Conductivity was proportional to silver content and dependent on hybrid formation method.
