The Surface Properties of End-functional Polymers

This article reviews the recent progresses on the surface properties of end-functionalized polymers.The end-functionalization of polymer was a robust method to modify polymer surface.The kinds and the number of functional groups on the polymer surface can be precisely controlled by this method,which result in affecting the chemical structure and properties of polymer surface.The segregation phenomenon of end-functionalized groups of the polymer was discussed.Some analysis techniques such as SFG,NR and SSIMS,employed to characterize the surface of end-functionalized polymer were introduced.Surface reconstruction of end-functionalized polymers and the effect of end groups on the molecular movability on the polymer surface were discussed.It is pointed out that the polymer surface with desirable surface energy could be effectively achieved by changing the end groups of polymer.Forecast about application of end-functionalized polymer was presented.
