The conjugated microporous polyphthalocyanine-graphene composite laser protection material provided by the invention is an organic microporous polymer which takes graphene as a substrate and has a large delocalized pi electron conjugate structure, and has outstanding forgeability and thermal stability; strong three-order nonlinear optical response is shown, so a strong anti-saturation absorption effect is shown; and meanwhile, polyphthalocyanine can be uniformly attached to graphene and can be effectively prevented from being gathered.

Description

technical field [0001] The invention belongs to the field of laser protection materials, in particular to a conjugated microporous polyphthalocyanine-graphene composite laser protection material and a preparation method thereof. Background technique [0002] In recent years, with the continuous progress and expansion of laser science and technology, the research of laser protective materials has attracted more and more attention and attention. However, compared with the rapid development of laser technology, the development of laser protection technology is still in a particularly slow state, and the gap between laser technology and laser protection technology is getting farther and farther. Therefore, the research on laser protective materials at this stage has become an urgent need in all aspects of industrial production, military defense, and scientific and technological research. At present, laser protection materials reduce the light intensity and transmittance of lase...
