This transfer process is fast, stable, and capable of transferring a large-size graphene, which may promote the large-scale application of graphene."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Graphene electrochemical transfer method assisted by multiple supporting films","description":"Disclosed is a graphene electrochemical transfer method assisted by multiple supporting films, comprising: (1) growing graphene on a substrate, and then spin-coating a thin layer of photoresist on a s","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11264461","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.
