Abstract

The invention discloses a stimulation responsive spiral polyyne infrared radiation material which is prepared from bromine-containing alkyne copolymers and amphipathic double-bond containing monomersthrough atom transfer radical polymerization, the material has a structure formula shown in the specification, in the formula, R1 is one of formulae shown in the specification, the polymerization degree m is an integer of 1-1000, n is an integer of 1-1000, and q is an integer of 1-1000. By using an atom transfer radical polymerization method, stimulation responsive spiral polyyne infrared radiation materials of different stimulation response are prepared from the bromine-containing alkyne copolymers and the amphipathic double-bond containing monomers, and through change of temperatures and pHvalues, low infrared emission rate regulation and control at a wave band of 8-14[mu] m are achieved. Meanwhile, the material is simple and convenient in preparation process, gentle in reaction condition, and good in thermal stability and infrared radiation performance regulation and control.
