New Horizons in Cationic Photopolymerization
In this review, we report some recent advances and new horizons in UV-induced cationic photopolymerization. In particular, after a brief introduction on the discovery and affirmation of the cationic photopolymerization process, new efforts in the synthesis of cationic photoinitiators are reported. Subsequently, an interesting and absolutely new application is reported, related to the combinatio...
متن کاملHigh dynamic range cationic two-photon photopolymerization
Cationic-induced two-photon photopolymerization is demonstrated at 710 nm, using an isopropylthioxanthone / diarylidonium salt initiating system for the cationic polymerization of an epoxide. The polymerization threshold J2th is found to be approximately 1 GW/cm, with a dynamic range of > 100, i.e. the material can be fully polymerized at intensities > 100 times the threshold level without dama...
متن کاملNew visible light photoinitiating systems for free radical and cationic photopolymerization
In this paper, visible light photoinitiating systems are developed for Free Radical Photopolymerization FRP and Free Radical Promoted Cationic Photopolymerization FRPCP. In the former case, the use of a pyrromethene dye was found to yield high rate of polymerization as well as high final conversion when combined with an amine and a redox additive such as a triazine. The mechanism of reaction wa...
متن کاملOrigami by frontal photopolymerization
Origami structures are of great interest in microelectronics, soft actuators, mechanical metamaterials, and biomedical devices. Current methods of fabricating origami structures still have several limitations, such as complex material systems or tedious processing steps. We present a simple approach for creating three-dimensional (3D) origami structures by the frontal photopolymerization method...
متن کاملHolographic characterization of chain photopolymerization
A holographic characterization technique is developed in accordance with a general photopolymerization model. The technique allows detailed quantification of the chemical parameters, including their variation from the Trommsdorff effect. The holographic procedure is especially suited for studying the diffusion of the chemical reactants. © 1999 Optical Society of America [S0740-3224(99)01408-3] ...
