Abstract: A new humidity sensor based on graphene oxide quantum dots (GOQDs)/polyelectrolyte [polymer (diallylimethyammonium chloride) (PDDA)] composite sensing films was proposed. A few layers of GOQDs anchor on PDDA were prepared on the substrate via covalent bonds. A 0D scale, hydrophilicity, and super-permeation of GOQDs endow the sensor an ultrafast response with about 32 ms response time and 48 ms recovery time. Meanwhile, the response was hardly affected due to covalent anchor of the composite film even after the sensor was soaked in water for several times.
