AB  - Processing and characterization of polymer nanocomposites based on poly(methyl methacrylate) (PMMA) matrix with embedded core-shell CdSe/ZnS quantum dots were investigated. Nanocomposites were obtained via solution casting and electrospinning. FESEM analysis revealed that the processing with electrospinning enables better dispersion of quantum dots. Time-resolved laser induced fluorescence measurements confirmed uniform size of QDs in fibers with the emission at only one wavelength. Oxidation effects in quantum dots were removed with the use of PMMA as a host, and the core remained active, which was confirmed with FTIR analysis and time-resolved laser induced fluorescence measurements.

AB  - In the present paper an effort has been made to investigate processing and characterization of composite poly (methyl methacrylate)-cadmium selenide (PMMA-CdSe). Thin films of pure PMMA and composites with 0.06 % wt. CdSe quantum dots nanoparticles were made using solution casting method. Characterization of starting components and composites was performed in order to obtain information of their morphology, structure, thermal stability, mechanical and optical properties. Nanoindentation revealed mechanical improvements with the addition of the crystal through reduced elastic modulus and hardness values. DSC analysis has shown an increase in T-g for composite with CdSe. Optical studies by time resolved laser induced fluorescence (TR-LIF) showed that the size-tunable optical properties can be achieved in the polymer films by addition of quantum dots.

AB  - This article presents a novel processing method of a self-healing acrylic thermoplastic material starting from a healing agent in solution form. The self-healing system consisted of a solution of the healing agent dicyclopentadiene (DCPD) in dimethylformamide (DMF) and a solution of the catalyst bis(tricyclohexylphosphine) benzylidene ruthenium (IV) dichloride (called Grubbs' catalyst) in dichloromethane (DCM). Hollow glass tubes filled with the self-healing components were incorporated into autopolymerizing acrylic resins. The one set of tubes was filled with a solution of DCPD (containing the dye Rhodamine B as a marker) and the other set with a solution of Grubbs' catalyst in dichloromethane. FTIR and DSC analyses revealed that a poly(DCPD) film formed at the healed interface. The low energy impact tests of the samples showed a recovery of 83% after 4 days. The benefits of the Grubb's catalyst solution are twofold; besides the repair of the cracks, which is common for such a system, the reaction could decrease the content of residual monomer in the acrylic resin, which could reduce diffusion of residual monomer out of the resins.
