LASER SYNTHESIS OF SELENIUM NANOPARTICLES IN LIQUID MONOMERS

Abstract

The paper presents the results of selenium nanoparticles synthesis in various liquid monomers by laser ablation. The following substances were selected as the condensation liquids for laser ablation: isodecyl acrylate (IDA, Isodecylacrylate, Aldrich), carboxyethyl acrylate (2Car, 2-carboxyethyl acrylate, Aldrich), ethylene glycol phenyl acrylate (Aldrich), ethylene glycol phenyl acrylate, an available blend of Ebecryl monomers (Cytec Industries Inc.), currently one of the possible components of modern lacquer coatings for nail plates. Thus, a method is proposed for simultaneous synthesis and incorporation of selenium nanoparticles into a polymer matrix. It is established by scanning microscopy method that the sizes of the obtained nanoparticles are from 50 to 200 nm. Infrared spectroscopy results of obtained colloidal solutions showed zero interactions of selenium nanoparticles with monomers. Stable colloidal solutions of selenium nanoparticles were obtained, and solid polymer films promising for biomedical applications were synthesized. The polymerization of colloidal solutions with added monomers and/or mixtures of oligomers was carried out using photo initiator of polymerization 2.2-dimethoxy-2-fenilatsetofenol, sensitive in the UV region (365 nm). The results of IR spectroscopy of the obtained colloidal solutions and polymer nanocomposites showed the absence of interactions of selenium nanoparticles with monomers and polymer matrices. Such nanocomposites could be perspective for biomedical applications, for example, as fungicidal coatings of different surfaces.
