The XPS variational angle depth analysis method can be used to analyze the composition and structure of interfacial and surface layers at the molecular level. It is of high sensitivity, has a wide application region, is a non-destructive and simple experimental method; therefore, it is a new kind of practical interfacial depth analysis technique. According to the depth analysis of the composite interfacial layer between polyacrylamide and monocalcium aluminate, at the interfacial mutation region, there exists great variation in the concentration of different elements and their chemical shifts and O enrichment, which shows the mechanism of forming of the C-O bond. In the interfacial layer, C, N and O in the polymer diffuse with difficulty into the inorganic matrix; this is because the polymer has large molecules, on the contrary, the diffusion ability of the inorganic ion Ca and Al in the inorganic matrix is greater. This shows that the reaction between the organic and the inorganic substances is performed by the diffusion of the inorganic matrix to the polymer.
