Abstract AITranslate

This work reports several 1,5-diaminoanthraquinone (1,5-DAAQ)-based visible-light-sensitive photoinitiating systems (PISs), which can efficiently initiate the free radical photopolymerization of (meth)acrylates under green light delivered from light-emitting diode. The PISs contain three components: 1,5-diaminoanthraquinone, an iodonium salt, and aromatic amines. In one example, polymerization could be efficiently initiated and completed within 10 s with double bond conversions of approximately 80%. The initiating system could also be used in conjunction with reversible addition–fragmentation chain transfer (RAFT) polymerization. Finally, the 1,5-DAAQ/iodonium salt/4-N,N-trimethylaniline PIS could be readily employed in the 3D printing process of polymer/carbon nanotube nanocomposites.
