摘　　要：以壳聚糖为底物,通过简单的研磨法,掺入稀土盐和磺柳酸,合成了两种具有荧光性能的电流变体材料,并测定其组成、荧光性能和电流变性能。结果表明,各个原料之间发生了酸碱或配位反应,磺柳酸和稀土盐增强了壳聚糖的电流变性能。其中只含有铽离子的磺柳酸壳聚糖复合材料具有最好的电流变性能。复合材料的组成和结构是决定其电流变性能的主要因素。而且,含有铽离子的两种稀土复合材料具有荧光性能。Two luminescent and electro-rheological composite materials were synthesized by a simple grinding method of mixing chitosan, rare-earth salt and sulphosalicylic acid. The luminescent and electro-rheological properties were characterized. The results showed an acid-base or complex reaction happened among the starting materials. The electro-rheological property of chitosan has been enhanced by rare-earth salt and sulphosalicylic acid, among which with the one that contained terbium ion exhibited the highest electro-rheological property. The most important factors determining the electro-rheological property of the composites were composition and structure. Furthermore, composites containig terbium ion exhibited luminescent property.
