“…2 and Table 4) under a laser diode at 457 nm or very soft halogen lamp. It is usually used in combination with amines [140,141], however, the development of CQ based initiating systems for dental applications remains very important [142,143]. Unlike other parent systems, the CQ/Iod or CQ/Iod/NVK combination is not efficient for the FRPCP of EPOX upon the halogen lamp or the laser diode at 457 nm exposure, but the CQ/Iod/silane works quite well under a Xenon lamp [144].…”

“…Among the various methods applied to graft polymers on various substrate surfaces, photochemicals protocols serve significant advantages due to a wide range of ecological, energetical and financial expectations . These advantages include temporal control, low‐energy requirements, high rates of polymerizations at ambient temperatures without the necessity of using volatile organic solvents giving rise to environmental and health‐care benefits.…”

The surface chemistry of aryl diazonium salts has progressed at a remarkable pace in the last two decades, and opened many avenues in materials science. These compounds are excellent coupling agents for polymers to surfaces via several surface‐confined polymerization methods. For the first time, we demonstrate that diazonium salts are efficient for surface initiating radical photopolymerization in the visible light of methyl methacrylate (MMA) and 2‐hydroxyethyl methacrylate (HEMA) taken as model monomers. To do so, 4‐(dimethylamino)benzenediazonium salt was electroreduced on gold plates or flexible ITO sheets to provide 4‐(dimethylamino)phenyl (DMA) hydrogen donor layers; while excited state camphorquinone acted as the free hydrogen abstractor. In the same way, we co‐polymerized HEMA and MMA with ethylene glycol dimethacrylate in order to obtain crosslinked polymer grafts. We demonstrate by XPS that gold was efficiently screened by the polymer layers and that the wettability of the surfaces accounts for the hydrophilic or hydrophobic characters of the tethered polymers. Homo‐ and crosslinked PMMA grafts were found to resist removal by the paint stripper methyl ethyl ketone. The grafted DMA/camphorquinone system operating in the visible light holds great promises in terms of adhesion of in situ designed continuous or patterned polymer coatings on various substrates. © 2016 Wiley Periodicals, Inc.

This review article is a comprehensive study of different approaches utilized by various researchers for UV-cure epoxy composites through the cationic route in the form of transparent or colored composites either in thin films or thick dimensions. Generally UV curing is applied on thin and transparent materials, yet attempts are being made to cure intensely colored and thick composite samples. In recent times, thick sample UV-curing has been actively explored to decrease the processing and fabrication expenses of complex assemblies. In this article, data has been reviewed about epoxy curing with methodological trends, not only in thin films but also in thick samples.
