Abstract

本发明公开一种用于紫外光强度检测的组合物、薄膜、制备方法和检测方法,涉及光学检测技术领域,在实现大面积的紫外光强度检测的同时,降低检测过程复杂度。该组合物包括向列相混晶、手性添加剂、胆甾相液晶、偶氮苯类单体、光可聚合物单体和光引发剂;所述薄膜包括上述技术方案所提的组合物,制备时,将组合物中的各个组分混合均匀并进行铺展,形成混合体系预制膜层,并通过紫外光照射,得到薄膜。本发明提供的组合物用于紫外光强度检测。
The invention discloses a composition, a film, a preparation method and a detection method for detecting the intensity of an ultraviolet light, and relates to the technical field of optical detection, aiming at detecting the intensity of large area of ultraviolet light as well as lowering complexity in the detection. The composition includes a nematic phase mixed crystal, a chiral additive, a cholesteric liquid crystal, an azobenzenes monomer, a light polymerable monomer and a photoinitiator. The film includes the composition provided by the technical solution. Upon preparation, each component of the composition is evenly mixed and spread to form a mixed system pre-fabricated film layer which is radiated by ultraviolet light, thus preparing the film. According to the invention, the composition is intended for detecting the intensity of the ultraviolet light.
