制备了 CMC/Eu(Ⅲ)、CMC/Tb(Ⅲ)、HPCMC/Eu(Ⅲ)、HPCMC/Tb(Ⅲ)纳米复 合物，通过 XPS、UV-Vis、流变学检测及 TG-DSC 研究了产物的“天线效应”、荧光性质、静 态/动态流变性质以及热性质． XPS 结果表明，Eu³⁺ 、Tb³⁺ 与 CMC、HPCMC 均生成 Ln(Ⅲ)—O，而且产物的紫外吸收与其激发光谱有重叠，证明纤维素衍生物所吸收的能量 可以成功地转移到稀土金属，使之发光;流变学性能研究结果表明，前述 4 种纳米复合物 溶液均为假塑性流体，黏流活化能分别为 1. 5964、2. 5193、1. 6047 和 1. 4218kJ/mol，其黏 度对温度具有依赖性;溶液的储能模量和损耗模量均随角频率的增大而增大;纳米复合物 与 CMC-Na、HPCMC-Na 有相似的热性质，且 HPCMC 侧链更易与水通过氢键结合．

CMC/Eu(Ⅲ),CMC/Tb(Ⅲ),HPCMC/Eu(Ⅲ),HPCMC/Tb(Ⅲ) nanocomplexes were prepared,and the “antenna effect”,fluorescence properties,static and dynamic rheological properties and thermal properties of the products were investigated by means of XPS,UV-Vis,rheological detection and TG-DSC.XPS results show that Ln(Ⅲ)—O is formed in all the products of Eu³⁺ and Tb³⁺ reacting with CMC and HPCMC,and the UV ab- sorption of the products overlaps its excitation spectrum,which proves that the energy absorbed by cellulose deriva- tives can be successfully transferred to a rare earth metal to make it light.The results of the rheological properties of the nanocomplexes show that the solutions of all nanocomplexes are pseudo-complex,and the flow activation energy of the four kinds of nanocomplexes are 1. 5964,2. 5193,1. 6047 and 1. 4218kJ/mol respectively,suggesting that the viscosity is dependent on temperature.In addition,the storage modulus and loss modulus of the solution grow up with an increase of the angular frequency; the thermal properties of the nanocomplexes are similar to those of CMC-Na and HPCMC-Na,and the side chains on HPCMC are more readily associated with water through hydrogen bonding.
