The rapid progress of the intelligent industry has led to an increasing demand for high-performance sensors in various fields.Traditional sensors have limitations in terms of sensitivity,selectivity and stability,and they are difficult to meet the detection requirements in complex environments.Polymer materials have stable physical and chemical properties,with designability in molecular structure and size,and they are also flexible and easy to process.The special electronic structure of rare earth ions can endow polymers with unique optical and electrical properties.Based on this design,polymer-based rare earth sensors can provide stable microenvironments for rare earths and endow the materials with good processability and mechanical properties.This paper reviewed the characteristics and action mechanisms of rare earths in polymer-based rare earth sensors,as well as the manufacturing methods and application progresses of polymer-based rare earth sensors.It is found that polymer-based rare earth sensors exhibit high sensitivity and selectivity in specific detection scenarios,but they still face problems such as poor stability,complex preparation processes,and high costs.Future research should be focused on optimizing the stability of ligands and polymer matrices as well as packaging technologies,enhancing the specific recognition of target objects and signal amplification capabilities,reducing the interferences of environmental factors on sensors,and improving the stability and sensitivity of polymer-based rare earth sensors,so as to expand their applications in the fields of multi-dimensional,high-precision,and wearable multimodal sensing technologies.
