Abstract The synthesis and characterization of luminescent hybrid composites based on bisphenol A glycerolate (1 glycerol/phenol) diacrylate (BPA-Acr) as a cross-linking monomer and N-vinylpyrrolidone (NVP) as an active diluent, in the presence of UV initiator (Irgacure 651), are presented. Eu(III) and Tb(III) carboxylate complexes were added as luminescent components of composites. In their preparation, a constant concentration of the initiator (1%) and the BPA-Acr to NVP (10:3) ratio were applied. The structures of the obtained materials were confirmed by the infrared spectra (ATR-FTIR). Thermal properties of the cross-linked products were determined by different thermal analysis methods in air and nitrogen (TG–DTG–DSC and TG–FTIR). Thermal stability, pathways of thermal decomposition and volatile products of degradation were determined. Photoluminescence properties of the lanthanide complexes and the obtained composites were established. These materials can have the potential application as coatings filtering harmful UV radiation.

Microindentation Technique

Polystyrene–polybutadiene block copolymers having different molecular architectures were epoxidized by using meta-chloroperoxybenzoic acid (MCPBA). Then, the blends with epoxy resin (diglycidyl ether of bisphenol-A; DGEBA) and their nanocomposites with boehmite and layered silicate nanofiller in presence of methylene dianiline (MDA) as a hardener were prepared. The epoxidized copolymers and the composites were characterized by Fourier transform infrared (FTIR) spectroscopy and microindentation technique. In this way, it was possible to tune the morphology of the nanostructured blends of the epoxy resin using the functionalized block copolymer as the template. The presence of nanostructured morphology was attested by the optical transparency of the blends as well as of the composites with nanofiller. The microhardness properties were improved by the incorporation of the nanoparticles, viz. boehmite and layered silicate.
