【摘要】：一个多世纪以来,凝胶作为介质被用于晶体生长,成功制备出了大量单晶.其中,越来越多的单晶被证明能在晶体生长过程中将凝胶网络嵌入其中,从而形成两相三维互穿的凝胶网络-单晶复合物,这与自然界生物体中大分子嵌入单晶内部以增强晶体力学性能的现象如出一辙.兼具单晶的长程有序特征和复合材料的综合特性使得这种单晶复合物受到研究者的广泛关注.本文综述了凝胶法制备凝胶网络-单晶复合物的研究进展,对具体技术手段、单晶中凝胶嵌入的表征、影响凝胶在单晶中内嵌的因素以及单晶复合物的功能化4个方面进行了介绍和讨论,并对今后的研究方向与前景进行了展望.
[Abstract]:For more than a century, gel has been used as a medium for crystal growth and a large number of single crystals have been successfully prepared. Among them, more and more single crystals have been proved to be able to embed the gel network in the process of crystal growth, thus forming a two-phase three-dimensional interpenetrating gel network-single crystal complex. This is similar to the phenomenon that macromolecules are embedded in single crystals in nature to enhance the mechanical properties of crystals. Both the long-range ordering of single crystals and the comprehensive properties of composite materials make this single-crystal complex attract wide attention. In this paper, the research progress in the preparation of gel network-single crystal complex by gel method is reviewed, and the characterization of gel intercalation in single crystal is given. The factors affecting the inclusion of gel in single crystal and the functionalization of single crystal complex were introduced and discussed, and the future research direction and prospect were also prospected.
