摘　　要：通过原位生长法制备出了金属有机骨架化合物修饰(MOFs)的功能纸,采用FTIR、XRD、SEM、BET、TGA分别表征了金属有机骨架化合物与纸张之间的结合方式、表面形貌、比表面积、吸附性和热性能,并对其热机理进行了分析.结果表明,MOFs与纸张纤维以氢键的方式相互结合,分子内氢键和分子间氢键协同作用增强了MOFs修饰功能纸(Paper@MOFs)的热性能;其次,经MOFs修饰后,功能纸的比表面积和吸附性能均获得了显著提高,这说明MOFs修饰功能纸是一种潜在的具有优异热稳定性能的气体吸附材料.In this work,we prepared Metal-Organic Frameworks （MOFs）modified paper via In-Situ Growth method.Then,the binding mode between MOFs and traditional paper,sur-face morphology,specific surface area,gas-adsorption and thermal properties of Paper@MOFs were characterized by FTIR,XRD,SEM,BET,TGA.The results showed MOFs and paper fiber were bonded of hydrogen bonds,the synergistic effect of inter-molecular hydrogen bonds and intra-molecular hydrogen bonds enhanced thermal property of MOFs modified pa-per.Also,specific surface area and gas-adsorption of MOFs modified paper was increased sig-nificantly.It also shows that MOFs modified paper is a potential gas adsorptive functional material with thermal performance.
