Arrangement of fluorine-containing group side chains on the latex film surface

The self-crosslinking fluorine-containing latex film was attributed and characterized with Static Contact Angle Instrument and X-ray Photoelectron Spectrum ( XPS), and then the surface free energy of the latex film was calculated by the use of experimentation and group contribution method respectively. The purpose is to examine the arrangement of fluorine-containing group side chains on the latex film surface. The results show that the surface free energy of the latex film can be decreased along with increase of fluorine containing monomer amount when its amount is below 20. 3%, but that when above 20. 3%, variation of surface free energy of the latex film is less and the fluorine-containing latex film has a strong self-recovery capability. Further studies on the film surface show that the arrangement of fluorine containing group side chains on the latex film surface is random and irregular.
