摘要
在经典成核理论基础之上,综述了无机、有机化合物和大分子聚合物等几类物质在不同的限域空间内的结晶行为,并与普通溶液结晶行为进行了比较。分析了不同限域空间对晶体的成核、生长以及相转化产生的影响,如成核速率、生长取向、晶型种类等。研究表明,在高度分散的纳米孔基质中,孔径尺寸、形貌对晶体成核与生长的控制机理不同,从而影响了最终的晶体结构。
The crystallization behaviors of inorganic,organic compounds and macromolecular polymers in different confined spaces are reviewed based on the classical nucleation theory,and the crystallization behaviors in ordinary solutions are compared.The effects of different confinement spaces on the nucleation,growth and phase transformation of crystals,such as nucleation rate,growth orientation,crystal type,etc.,are analyzed.Studies have shown that different pore sizes and morphologies have different control mechanisms for crystal nucleation and growth in a highly dispersed nanoporous matrix,thereby affecting the final crystal structure.
