Abstract: Cellulose has attracted wide attention of researchers because of its biocompatibility, flexibility,
degradability and recyclability. Cellulose-based conductive hydrogels as novel flexible materials have been
widely used in electronic materials and biomedical applications due to their good electrical conductivity,
excellent self-healing properties and high mechanical strength. Herein, the cross-linking mechanism of
cellulose-based conductive hydrogels was firstly introduced. Their classification based on the self-healing
properties, high mechanical properties, adhesion properties and freezing resistance was then discussed,
followed by review on the research progress on applications in sensors, capacitors, batteries and biomedical
materials applications. Finally, the research prospect on cellulose-based conductive hydrogels was
summarized with the research on multifunctional and green cellulose-based conductive hydrogels as the
main trend of future development.
