利用氧化石墨烯(GO)和罗丹明6G-聚乙烯亚胺(R6G-PEI)对滤纸(FP)进行物理改性,制备了纸基传感器FP/GO/R6G-PEI.利用扫描电子显微镜、X-射线衍射仪、伺服材料多功能高低温控制试验机、紫外光谱仪和荧光光谱仪等,对FP/GO/R6G-PEI的形貌、力学性能和传感性能进行表征.结果表明,与FP、FP/GO相比,FP/GO/R6G-PEI的表面平滑度提高,透气度降低,力学性能增大.将FP/GO/R6G-PEI浸泡于Fe3+溶液中时,观察到FP/GO/R6G-PEI变为淡粉红色,且荧光强度显著增强,可实现FP/GO/R6G-PEI对水中的Fe3+肉眼可见和荧光检测.理想识别单元Structure 3与Fe3+的能级差(0.53 eV)小于Structure 3的能极差(3.12 eV),说明Structure 3与Fe3+的螯合体系更稳定.
Preparation and Properties of Graphene Oxide/Rhodamine 6G Modified Filter Paper
The paper-based sensor FP/GO/R6G-PEI was prepared by physically modifying the filter paper(FP)with graphite oxide(GO)and rhodamine 6G-polyethyleneimine(R6G-PEI).The morphology,mechanical properties,and sensing performances of FP/GO/R6G-PEI were characterized by scanning electron microscope,X-ray diffraction,servo material multi-functional high and low temperature control test-ing machine,UV-vis spectrometer,and PL spectrometer.Compared with FP and FP/GO,the surface smoothness and mechanical property of FP/GO/R6G-PEI increased,while the air permeability decreased.When FP/GO/R6G-PEI was immersed in Fe3+solution,it was observed that FP/GO/R6G-PEI turned pale pink,and the fluorescence intensity was significantly enhanced,which realized the visual detection and fluorescence detection of FP/GO/R6G-PEI to Fe3+in water.The energy gap between Structure 3 and Fe3+(0.53 eV)was obviously smaller than that of Structure 3(3.12 eV),indicating that the chelating system was more stable after the interaction of structure 3 with Fe3+.
