纳米材料的结构与性质

纳米材料是近几年最受关注的新材料之一,以其高表面活性,特殊的尺寸效应、光电效应、催化效应、广阔的应用前景等特点成为当今热点研究领域之一。当物质的结构单元小到纳米数量级时,会产生特异的表面效应、体积效应和量子效应,其电学、磁学、光学和化学性质也相应地发生显著性的变化,呈现出常规材料不具备的优越性能。

Structure and Character of Nano-Materials

Nano-materials are one of the novel materials which scientists are paying more and more attention,due to its high surface active,special size effect,photoelectric effect,catalytic effect and wide application potential.When the size of material decreases to nano scale level,special surface effect,volume effect,quantum effect were observed,electrical character,magnetic characters,optical character and chemical characters of material changed greatly.Nano-materials have high performance,but none of normal mater...
