| 摘 要： | 采用X射线光电子能谱(XPS)研究了双梳型共聚物吸附于莠去津颗粒样品表面的电子状态,计算了吸附厚度.结果表明:吸附后,莠去津颗粒界面的N 1s和Cl 2p谱峰强度明显减弱,Cl 2s几乎消失,而C 1s和O1s谱峰强度则明显增强,这主要是双梳型共聚物中C和O的贡献,且吸附后能在莠去津颗粒界面形成良好的吸附保护膜,其厚度...

| Abstract: | The electron state of adsorption of double comb shape copolymer on the surface of atrazine particles was observed with X-ray photoelectron spectroscopy and the adsorption layer thickness was also calculated.After the adsorption,the absorption strength of N 1s and Cl 2p on the interface of atrazine particles decreased sharply and the absorption peak of Cl 2s almost diminished.Because of the contribution of C and O in the dispersant,the absorption strength of C 1s and O 1s on the interface increased.Moreover,... |
