Bài báo trình bày quy trình nghiên cứu chế tạo graphene khử tách nhiệt và biến tính với polyvinyl alcohol (PVA) ứng dụng làm sơn nước dẫn điện trên cơ sở polyurethane (PU). Graphite oxide (GO) được oxit hóa từ graphite theo phương pháp Hummer, sau đó graphene được tạo thành bằng phương pháp khử tách nhiệt GO. Graphene được biến tính bằng cách phân tán vào dung dịch PVA với nhiều nồng độ và tỷ lệ khối lượng khác nhau để tối ưu hóa quá trình biến tính...
