摘　　要：本文分别从纳米材料的热容、晶格参数、结合能、内聚能、界面能、界面应力、热稳定性、熔点、熔解焓、熔解熵、相图及纳米材料参与反应时反应体系的化学平衡、吸附能等方面对纳米材料热力学的研究进展进行了阐述,并对纳米材料热力学的研究和应用前景进行了展望。Nanomaterials have attracted great interest in recent years because of their unusual mechanical,electrical,optical,magnetic and surface properties.Recent investigations have also shown that nanoscale materials can offer certain physical and chemical effects.There is no doubt that the employments of materials are closely related to their thermodynamic properties which are considered to be the fundamental factors for the studies of materials.However,the thermodynamic properties of nanomaterials are usually different from their bulk materials.Thus,it is very important to study the thermodynamics of nanomaterials.The review focuses the status of research on thermodynamics of nanomaterials including heat capacity,lattice parameters,binding energy,cohesive energy,melting enthalpy and other thermodynamic functions.In addition,the development trend in this field is prospected.
