Preparation and Performance Study of Reduced Graphene Oxide/Carboxymethyl Cellulose Flexible Temperature Sensor Based on Polyurethane Membrane
摘要
Abstract
Flexible temperature sensors with high temperature sensitivity and reliable repeatability play a crucial role in the emerging field of electronic skins.A flexible temperature sensor was synthesized by dissolving carboxymethyl cellulose(CMC)in graphene oxide solution(GO)and using polyurethane membrane(PU)encapsulation.The prepared sensor has an excellent temperature sensitivity coefficient(1.54%/K),fast response time(9.2s)and reliable monitoring repeatability.It is worth noting that the introduction of CMC increases the conductive barrier between the reduced graphene oxide(rGO)sheets,which effectively improves the temperature sensitivity coefficient of the rGO@CMC composite.Meanwhile,the packaging of PU film prevents the interference of oxygen and water molecules,which greatly enhances the service life and stability of the sensors.In addition,the flexible temperature sensor shows excellent detection accuracy and detection stability in practical applications such as continuous temperature monitoring and respiratory rate measurement,demonstrating its wide applicability in electronic skin applications such as medical monitoring,intelligent robotic platforms and environmental detection.关键词
