Epoxy resins have been used in a wide range of field such as paints, adhesive, civil engineering and semiconductor packaging because of their outstanding chemical, thermal, mechanical and electrical characteristics. However, these performances of epoxy resins are greatly affected by the absorbed moisture which results in volume expansion, cracks, and the decreased glass trasition temperature. In this study, to solve this problem, polyhedral oligomeric silsesquioxane (POSS), which is the smallest silica particle containing silica-like core and organic functional groups, was selected to restrict chain movement and bisphenol A dicyanate (BADCy) was used to prevent the moisture absorption of epoxy. Glycidyl POSS/BADCy was synthesized via in-situ process in the epoxy network. Finally, we prepared the nanocomposites of epoxy and cyanate ester functionalized POSS and analyzed moisture absorption property, thermal, and electrical behaviors. |
