Abstract

The invention relates to a phthalocyanine polymer, an optical limiting device and a preparation method therefor. A special synthetic technique is adopted for synthesizing an asymmetric phthalocyanine compound containing monohydric radicals, and then epoxy resin adhesive monomers with excellent performance after curing are selected, so that the hydroxide radicals of the asymmetric phthalocyanine perform a polymerization reaction with an epoxy group of the adhesive, the phthalocyanine is grafted onto the epoxy resin monomers, and then a curing polymerization reaction is carried out continuously under a modified flexibilizer and a curing agent so as to obtain a low molecular polymer system containing a phthalocyanine unit. The phthalocyanine in the polymer system is uniformly distributed in the whole polymer structure in a single-molecule monomer structure; compared with a traditional doped hybrid and LB film low molecular sol-gel composite method, the phthalocyanine polymer has higher uniformity, transparency, strength, chemical stability and processing stability performance; and the prepared optical limiting device has good optical limiting performance and mechanical performance.

Description

【Technical field】 [0001] The invention relates to a phthalocyanine polymer, a preparation method of the phthalocyanine polymer, an optical limiting device, and a preparation method of the optical limiting device. 【Background technique】 [0002] With the rapid development of laser technology, the performance of laser weapons is becoming more and more superior, and the damage caused by them is also increasing. Therefore, countries have begun to intensify their research on laser protective materials. Phthalocyanine compounds are a class of light-limiting materials with very promising application prospects. The light-limiting effect is not limited to the visible light region, but can also reach the near-infrared region, which makes phthalocyanine compounds can be used in tunable broadband laser weapons protection. In addition, phthalocyanine compounds also have the characteristics of obvious limiting effect and rapid response, which are of great significance for the research o...
