摘要： 用原子力显微观测(AFM)研究了不同质量浓度的疏水缔合聚合物(AP-P4)溶液在云母片上的结构形貌。观察到疏水缔合聚合物的质量浓度对结构形貌具有决定性的影响，在不同质量浓度下，其结构形貌有很大不同。质量浓度在200 mg/L 时，溶液结构主要是以聚集体的形式存在；当质量浓度大于500 mg/L 后，其结构发展为空间网状结构。AFM 这种方法有助于了解疏水缔合聚合物分子形态及其凝胶结构，同时也有助于研究疏水缔合聚合物溶液的结构。

Abstract: The structure images of hydrophobic associated polymer (AP-P4) solution with different concentrations on mica slice is studied using atomic fore microscopy (AFM). The effect of the concentration on the structural image is confirmed definitively. It means that the images are quite different in different concentrations. When AP-P4 solution concentration is at 200 mg/L, its structure mainly appears in form of aggregates; at 500 mg/L, it occurs in form of spatial reticular structures. This method is helpful to understand the molecular images and the gel structures of AP-P4 and to study the solution structure of the polymers.
