Abstract
New meta- and para-cyanoderivatives of 1,4-di(styryl)benzene and 1,3-di(styryl)benzene were synthesized and investigated for their use as photosensitizers of iodonium salt for various photopolymerization processes. Detail spectroscopic characteristic of this compound were performed, and the mechanism of initiation in binary photoinitiating system together with iodine salt was discussed and confirmed by experiments. Using real-time FTIR, the usefulness of the proposed meta- and para-cyanoderivatives of 1,4-di(styryl)benzene and 1,3-di(styryl)benzene as highly efficient photosensitizers for various photopolymerization processes was tested, including: free-radical photopolymerization of acrylate monomer or cationic photopolymerization of epoxy and glycidyl monomers. In addition, the formation of interpenetrating polymer networks with the use of proposed two-component initiating systems was performed. Encouraged by excellent polymerization results with the use of the developed initiating systems, additional application tests were carried out, including: 3D printing using vat polymerization, visible based direct ink writing, preparation of various fiber-reinforced composite or formation of multiwalled carbon nanotubes composites (MWCNTs nanocomposites), for which the manufacturing process has been analyzed in detail using real-time FTIR method.
