Abstract

Parameters of photo-polymerization process (induction time, rate and degree of conversion) as well as the change of the refractive index, micro hardness and so of the resulting structure were investigated in urethane-acrylate based nanocomposites. Monomers were functionalized by adding SiO2 and Au nanoparticles by means of direct incorporation. The structural changes due to addition of nanoparticles and photo-polymerization were investigated by micro-Raman spectroscopy and X-ray diffraction (XRD). The real time changes in the refractive index due to irradiation were monitored by Surface Plasmon Resonance imaging (SPRi), which is a novel application of this platform. It is established that these nanoparticles have an influence on the polymer structure and on the transformation of selected bonds during the photo-polymerization process. The plasmon field of gold nanoparticles has a specific additional influence on these changes. These effects can be used to enhance surface relief recording in such nanocomposites due to the photo-stimulated mass transport of the nanoparticles embedded to the polymer matrix.
