摘要: Photo-induced thermal polymerization upon near-infrared (NIR) light irradiation has been reported in the literature. In this approach, a component able to convert NIR into heat must be used combination with initiator initiate free-radical of (meth)acrylates. recent studies, some absorbers have presented as very efficient generators (called heaters). present work, different fillers are investigated heaters and compared organic absorbers. An alkoxyamine (e.g., BlocBuilder-MA) is dissociated by generated photoexcitation fillers. several examined: graphene oxide, nanoplatelets, multi-walled carbon nanotubes, silicon carbide. Due energy photon delivered, curing challenging but offers advantages visible light. The most interesting feature deeper penetration inside photocurable resin, enabling thick samples. Parallel this, incorporation resins allows unique access composites through photothermal Three wavelengths studied: 785, 940, 1064 nm.
