A series of UV-heat hybrid curable compositions were prepared by using organosilicon modified epoxy monoacrylates(OMEMA) as resins.The change of absorption peaks of double bond and epoxy group were identified by FTIR spectra during UV-heat curing process.The influence of different kinds and content of active diluents on the gel content,water absorption and water contact angle of UV-heat cured films were investigated.Mass content of Si in surface of UV-heat cured films was tested by the energy dispersive spectrometer(EDS).The gel contents of UV cured films were lower than 86.5%,and the gel contents of UV-heat cured films were about 97%.Compared to the epoxy monoacrylates(EMA) compositions with same active diluents,the water contact angle of UV-heat cured films of OMEMA system was increased from 62.53 to 99.27.The data of EDS testing proved that the Si content of air side of UV-heat cured films was higher than glass side.

The curing rate and quantum efficiency of cationic photoinitiators are relatively low because the UV absorption of the photoinitiators ranges from 250 nm to 300 nm normally and does not match with the wavelength of light from UV light sources.To make the absorption red-shift,many efforts have been devoted onto the photosensitization of the photoinitiators.The achievements on the sensitization of the cationic photoinitiators have been summarized here.The sensitization is mainly based on the mechanisms as energy transfer,oxidation of free radical,electron transfer via exciplexes and addition fragmentation reaction.The methods adopted for the sensitization include adding photosensitizer,expanding molecular conjugation and attaching chromophore.The development of the photoinitiators and photosensitizers has been outlined and the applications of novel cationic photoinitiators and photosensitizers have been forecasted.
