近十几年中发展起来的纳米固体材料因其独特的物理、化学、力学性质和在众多领域的应用可能性而受到日益广泛的重视。热稳定性是材料的一项重要性质,在针对纳米材料热稳定性所进行的研究中,已经取得一些很有意义的结果,例如,发现不少纳米材料的热分析特性曲线上存在一个放热峰。但是,对于此放热峰的起因尚存有异议,有的认为是因晶粒长大而引起,而有的则归结于应力释放和界面原子的弛豫,他们在所研究的样品中都没有发现此 The nano-solid materials developed in recent ten years have been paid more and more attention because of their unique physical, chemical and mechanical properties as well as their application in many fields. Thermal stability is an important property of materials. Some interesting results have been obtained in the research on the thermal stability of nanomaterials. For example, it has been found that there is an exotherm on the thermal analysis of many nanomaterials peak. However, the cause of this exothermic peak is still objectionable, some are thought to be caused by grain growth, while others are due to stress relaxation and relaxation of interface atoms, none of the samples studied Find this
