Luminescent lanthanide metal-organic frameworks (ln-MOFs) is a promising materials for sensing. However,seeking ideal method to scale up in mass production and can be uniform on flexible substrate is still a great challenge. In thisstudy, a novel and efficient process was employed for the fabrication of flexible and environmental copper ion-sensingmaterials using cotton fabric as a substrate. The micro-nanoscale Europium metal-organic frameworks (Eu-MOFs) wasprepared through adding blocking reagent, and then cotton fabric was coated with the Eu-MOFs by hot pressing. The resultsshow that controllable dense micro-nanoscale Eu-MOFs film was coated on the cotton fabric with different dipping and hotpressing times. The method is fast, simple, low-cost and suitable for production. The Eu-MOFs coated cotton fabric exhibitsgood photoluminescent properties. The selective sensing ability of Eu-MOFs coated fabric for Cu2+ over many other metalions (K+, Cd2+, Ca2+, Pb2+, Na+, Zn2+, Ni2+, Mg2+, Al3+ and Co2+) is verified by emission spectra, and by the fact that thefluorescence intensity of the fabric significantly decreased with an increase in the concentration of Cu2+ (10-6-10-1 mol/L). This method provides a new path for the controllable production of MOFs-coated functional textiles for differentapplications, such as anti-counterfeiting, UV-protection, superhydrophobic, and sensing materials in the textile industry.
