文摘
- •
Graphene oxide/poly(ethyleneimine) layered film was first proposed to sense humidity.
- •
Three-dimension structure of folded GO sheets was formed due to redissolution effect.
- •
High sensitivity, low hysteresis and short response/recovery time were obtained.
- •
Water molecules adsorption sites and humidity-sensing models were built and discussed.
