| Summary: | The methyl acryloyloxy propyl silsesquioxane(MAP-POSS) was prepared by hydrolysis condensation of KH-570, and composing free radical-cationic hybrid UV curing system with the unsaturated epoxy resin. The changes of characteristic absorption peak in the curing process was characterized by using infrared spectroscopy (FT-IR), and the influence of MAP-POSS content on the surface water contact angle, silicon elements distribution, mechanical properties and thermal performance of UV-cured film was investigated. The results show that with the addition of MAP-POSS the crosslinking degree, hydrophobicity, thermal stability and glass transition temperature(<i>T</i><sub>g</sub>) of the film are improved. When the content of MAP-POSS is 12% (mass fraction, the same below), <i>T</i><sub>g</sub> is increased by 16.9℃. When the MAP-POSS content is 15%, the water contact angle of film is increased from 58.0° to 94.2°. The impact strength is improved firstly and then decreased with the addition of MAP-POSS. |
