中文摘要: |
纳米Si02是一种应用广泛、性能优异的无机材料。为了降低纳米二氧化硅的亲水性,提高亲油性,增强其与有机基体的相容性,从而充分发挥纳米Si02的纳米效应,需要对纳米Si02的表面进行改性。通过非均匀成核法,采用Al( OH)3对纳米Si02表面包覆改性以改善纳米Si02的表面结构和性能。使用IR、XPS、XRD和Malvem Zetasize 3000HSA自动电位粒度仪等表征手段,对表面包覆改性后纳米Si02的结构及等电点等进行了测试和分析。结果分析表明:Al( OH)3以无定形结构成功地包覆在纳米Si02表面,包覆后的纳米Si02仍为无定形结构,但其等电点(IPE)的pH值从2.3变为7.1。 |
英文摘要: |
Nano-Si02 is an inorganic materials with excellent properties and widely uses. In order to reduce the hydrophilicity, increase the hydrophobicity and improve the compatibility between organic matrix and nano-Si02 to make full use of its nano advantage, its surface need to be modified. Nano-Si02 surface was modified by Al( OH) 3 from heterogeneous nucleation process to improve the surface structures and properties. The surface structure and the zeta potential of nano-Si02 were characterized by IR, XPS, XRD and Malvern Instruments Zetasize Systems. The results indicate that nano-Si02 is successfully coated by amorphous Al( OH) 3 . After surface coating nano-Si02 is still amorphous and the isoelectric point of Si02 is changed from pH 2. 3 t0 7. 1. |
