近年来,纳米材料已在许多科学领域引起广泛的重视,成为材料科学研究的热点。所谓纳米材料,一般来说是指材料两相显微结构中至少有一相的一维尺寸达到纳米级的材料。由于纳米粒子较小的尺寸、大的比表面积产生的量子效应和表面效应,赋予纳米材料许多奇妙的力、光、电、磁 In recent years, nanomaterials have attracted a great deal of attention in many fields of science and become the focus of material science research. The so-called nano-materials, generally refers to the material two-phase microstructure of at least one-dimensional size of one-dimensional nano-scale materials. Due to the smaller size of nanoparticles, the large surface area of ​​the quantum effects and surface effects, giving nanomaterials many wonderful force, light, electricity, magnetic
