A novel photoinitiator called 2-methyl-2-benzoylethanolpentadecafluorooctanote (1173-F) was synthesized and characterized.1173-F is an efficient photoinitiator for free radical photopolyrnerization in the presence of oxygen and has ability of moving to the surface.The oxygen inhibition of the photopolymerization surface could be decreased because the large amount of photoinitiator at the top to be consumed by oxygen.UV absorption spectroscopy, X-ray photoelectron spectroscopy, and EDS-line mapping were used to prove that 1173-F can move to the surface in a short period of time both in the solvent and the monomers, forming a gradient distribution.Compared with the traditional photoinitiator, 1173-F can effectively decrease the inhibition of oxygen, and does not need to add any coinitiator or additives.The gradient distribution of fluorine containing photoinitiator can be used for preparing gradient material, and could be used as secondary polymerization.
