Temperature-dependent Optical Transmittance of Chemically Reduced Graphene Oxide/Hydroxypropyl Cellulose Assembly

Stable dispersion of chemically reduced graphene oxide (RGO) is prepared by simple noncovalent interaction with hydroxypropyl cellulose (HPC). Prepared RGO/HPC assembly shows temperature-dependent optical modulation below or above lower critical solution temperature (LCST). Different anchoring modes of HPC chains on RGO plates might contribute to the change of LCST for RGO/HPC assembly at different HPC-to-graphene mass ratio.
