摘要：

This paper reports different routes combining photopolymerization of epoxy and acrylate monomers or photo sol-gel reaction yielding to organic or hybrid nanocomposites with enhanced thermomechanical properties. First homogeneous Interpenetrating Polymer Networks based on a dimethacrylate and an epoxide were straightforwardly synthesized by means of UV curing without any phase separation. Then, a dimethacrylate resin was mixed with a variable amount of a methacrylate trialkoxysilane precursor. Upon UV irradiation, a dual organic-inorganic polymerization occurred in one step leading to increased scratch resistance. The structural properties of the resulting coatings were investigated by FT-IR and Si-29 solid state NMR spectroscopies. In addition, their thermomechanical behaviour was characterized by Dynamic Mechanical Analysis and scratch tests.
