摘要
利用接触角法研究了氨丙基硅烷化石英表面的基因浓度及单分子层中单个分子的截面积。提出了氨丙基硅烷化的模型。
In this paper,the concentration of amino group onto aminopropylsilanized(APS)quartz was measured by using contact angle method. Using phenol as a probe, the weak acid (phenol in CH_2I_2 solution)/the base(APS quartz) adsorption was studied in detail, and the surface concentration of amino group on APS surface was calculaled as 1.14 nm2/mole when the Langmuir isotherm was used. And further ,SAzoNC6OH acted as a probe, the surface adsorption concentration and molecular section area was indetified by using UV-visible absorption spectra. Comparing the area of per amino group of 0.41 nm2 from adsorption spectra measurement, a densed packing model, with hydrogen bonding existing between amino groups, was proposed.
