| 摘 要： | 通过半连续乳液聚合的方法获得了单分散性好，数均粒径为７０６９ｎｍ的苯乙烯，丙烯酸丁酯和丙烯酸（Ｓｔ／ＢＡ／ＡＡ）高分子微球，并通过毛细压力法，成功地在玻璃基体上组装成了紧密的二维有序排列点阵结构．点阵结构的形成过程可分为成核和增长两个阶段．在二维有序排列形成过程中，微粒之间的相互排斥作用可通过添加一定浓度的电解质来进行调节．组装后的二维有序排列用扫描电镜进行了观察．

| Abstract: | Uniform copolymer latex of styrene/butylacrylate/acrylic acid with 7069 nm numberaverage diameter was obtained by semicontinuous emulsion polymerization process. The ordered twodimensional arrays had been fabricated by the liquid capillary meniscus attraction force method. The formation process appeared to be in nucleation and growth stages. The interaction forces among particles could be controlled by adding a certain amount of NaCl electrolyte. The morphologies of the twodimensional arrays were observed by TEM images. |
