Their structure and water/oil repellency properties, such as surface property, water and chemical resistance of their membrane were characterized by fourier transform infared spectrometer (FT-IR), interfacial tension instrument (IT), contact angle (CA) and spot test.
In this work, their structure, and water/oil repellency properties were characterized by fourier transform infared spectrometer (FT-IR), interfacial tension instrument (IT), contact angle (CA) and spot test in details.
Results and Discussion FT-IR analysis The chemical structure of waterborne cationic perfluorinated polyacrylate (WCFPA) films was studied by FT-IR and the result is shown in Figure 1.
It is clear that the low surface energies of WCFPA films come mainly from the chemical structure of FEA, which has strong hydrophobic fluorinated groups.

Proper control of the pore structure of the supporting materials is critical to improve the performance of the composite PCMs [2].
Graphene oxide(GO) is a well-known layer-structured material obtained by oxidation of graphite.
In addition, according to the Clapeyron-Clausius equation, the layer structure of GO would not result in the pressure rise due to the volume restriction.

The structure and preparation methods of perovskite-type oxide catalysts are presented.
In the perovskite structure, although for an ideal perovskite t is unity with the highest symmetry in cubic structure.
However, this structure is also found for lower t-values (0.75 ≤t≤1.0).

Abstract.
The interfacial structure and interactions of amine-cured epoxy resin (EP) / aluminium oxidie system were investigated in this presentation.
The interphase structure and the morphology at different depths of the broken-surface of the samples were characterized by XPS and SEM.
XPS and SEM were adopted to characterize the interactions and interphase structure at different depths of the broken-interface of the composite materials.
But how to control and design the interphase structure should be conducted by further investigation.
