Efficient temperature sensing platform based on fluorescent block copolymer-functionalized graphene oxide.
نویسندگان
چکیده
Efficient temperature-sensing platform was demonstrated using temperature-responsive, fluorescent P7AC-b-PNIPAM-b-PSN3 block copolymer-anchored graphene oxide sheets (FGO). FGO exhibited extraordinary stability in water and showed fast optical on-off switching behavior in response to temperature change.

Mid-functionalized ABC triblock copolymers with a short central B block were synthesized via the RAFT process, and further used as well-defined V-shaped copolymers to graft onto graphene oxide by coupling reactions.
متن کاملSulfophenyl-Functionalized Reduced Graphene Oxide Networks on Electrospun 3D Scaffold for Ultrasensitive NO2 Gas Sensor
Ultrasensitive room temperature real-time NO₂ sensors are highly desirable due to potential threats on environmental security and personal respiratory. Traditional NO₂ gas sensors with highly operated temperatures (200-600 °C) and limited reversibility are mainly constructed from semiconducting oxide-deposited ceramic tubes or inter-finger probes. Herein, we report the functionalized graphene n...
