主　　题：near-infrared light photothermal conversion ketocyanine dye reversible-deactivation radical polymerization dividing wall-type heat exchange 

摘      要：As an effective means of utilizing light energy,photothermal conversion has excellent application in the field of ***,a dividing wall-type heat exchanger with the aid of photothermal conversion was designed to conduct polymerization under irradiation with near-infrared(NIR)light by utilizing the ketocyanine-type dye solution as the highly efficient activator(83.2%photothermal conversion efficiency).Various types of reversible-deactivation radical polymerization(RDRP)methods,including reversible addition-fragmentation chain transfer,atom transfer radical polymerization,and bromine-iodine transformation RDRP,are suitable for this ***-defined polymers with excellent control over molar mass and molar mass dispersity(D1.28)were thus synthesized within a few hours under NIR(λ_(max)=810 nm,850 nm)irradiation at room ***,in addition to conventional heating methods(such as electrical heating jackets),the designed dividing wall-type heat exchanger via NIR light activation has another unique advantage:it can enhance the polymerization by the synergistic effect of both heating and NIR light irradiation due to the deeper penetration of NIR light.
