The liquid crystal film comprises the composite material of the present invention, wherein the composite material comprises a polymer network of a cholesteric liquid crystal material, and a chiral material capable of hydrogen-bond-assisted self-assembly, and wherein the chiral material is dispersed in and restrained by the polymer network. The obtained liquid crystal film can exhibit a high reflectivity and a high transmittance as well as a broad band reflection. And, the liquid crystal film is applicable for an industrial development because it can be produced with a simple process and at a lower cost, and requires a lower UV luminous intensity."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Liquid crystal film, method for preparing the film, temperature-responsive device comprising the film, and circular polarizer made therefrom","description":"The present invention relates to a composite material, a liquid crystal film, a method for preparing the film, a temperature-responsive device comprising the film, and a circular polarizer made theref","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9631143","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
