“…However, due to the intrinsically exothermic nature of polymerization reaction, conventional FP lacks sufficient control over the front temperature. The temperature of thermal propagating fronts can rise to above 200 °C . The front temperature of conventional photo‐induced FP with persistent irradiation and low front velocity also reaches higher than 150 °C .…”

A novel approach of photo-triggered redox frontal polymerization (FP) by integrating photocaged superbase (QA-DBU) with a peroxide initiator (dibenzoyl peroxide, BPO) is presented for the synthesis of thermally sensitive materials. Under photo-irradiation at a localized region, the regenerated superbase can diffuse into unirradiated regions and effectively actuate redox FP in a diffusion-controlled manner. Moreover, the redox FP can be conducted at a much lower front temperature with enhanced front velocity. Astonishingly, the front temperature can be well-modulated by changing the concentration of latent superbase. The prepared thermally sensitive fluorescent polymer composites exhibit enhanced fluorescence emission intensity compared to that of conventional thermal FP. V C 2013

“…We could introduce a new concept of frontal polymerization involving a copolymerization-induced destabilization of (meth)acrylate-based peroxides that allows lowering the front temperatures. 205 This concept is based on the fact that with increasing the degree of branching of the substituent next to the carbonyl group of acylperesters, the decomposition temperature significantly drops. Thus, for the use of a peracrylate as a thermal initiator, the relatively high stability guarantees a good storage stability.…”

In the past 10 years, many new components were synthesized and evaluated for an application in enamel-dentin adhesives and direct composite restoratives. New bisacrylamide cross-linkers with improved hydrolytic stability and new strongly acidic polymerizable phosphonic acids and dihydrogen phosphates, as well as novel photoinitator systems, in combination with the implementation of novel application devices, have significantly improved the performance of the current enamel-dentin adhesives. The currently used resins for direct composite restoratives are mainly based on methacrylate chemistry to this day. A continuous improvement of the properties of current composites was achieved with the use of new tailor-made methacrylate cross-linkers, new additives, and photoinitiators as well as tailor-made fillers. Nowadays, dental adhesives and methacrylate-based direct restorative materials have found wide-spread acceptance. Nevertheless, future developments in the field of dental adhesives and direct composite restoratives will focus on improving durability and biocompatibility as well as the development of materials with a broader application spectrum and of smart adhesives or composites.
