石墨烯热管理材料！华为，小米争相搭载，它到底厉害在哪？

Core Viewpoint - Graphene thermal management materials are rapidly gaining popularity in the technology sector due to their exceptional thermal conductivity and versatility in various applications, particularly in consumer electronics and automotive industries [4][15]. Group 1: Graphene Thermal Management Materials - Graphene is recognized for its high thermal conductivity, with theoretical values reaching up to 5300 W/m·K, significantly outperforming traditional metals like copper and aluminum [6][8]. - The material's unique structure allows for efficient heat transfer, making it suitable for applications in smartphones, laptops, and electric vehicles [4][10]. - Major brands like Huawei and Xiaomi have successfully integrated graphene thermal materials into their products, showcasing its effectiveness in enhancing thermal management [4][5]. Group 2: Mechanisms of Heat Transfer - Heat conduction in graphene occurs through both phonon and electron interactions, which contribute to its superior thermal conductivity [5][12]. - The layered structure of graphene films affects heat transfer efficiency, with phonon scattering occurring at the interfaces between layers, impacting overall thermal performance [5][12]. Group 3: Advantages Over Traditional Materials - Compared to traditional thermal materials, graphene offers a combination of high thermal conductivity, flexibility, and lightweight properties, making it an ideal choice for modern electronic devices [8][10]. - Graphene thermal materials maintain their performance even after extensive bending and folding, unlike metals that may fracture or traditional thermal pads that may degrade over time [8][10]. Group 4: Industry Analysis - The graphene industry is experiencing rapid growth, particularly in China, which is leveraging its resources and manufacturing capabilities to develop a comprehensive graphene supply chain [15][16]. - The competitive landscape includes numerous players, but the high technical and financial barriers to entry limit the threat from new entrants [16][17]. Group 5: Representative Companies - Companies like Shenzhen Hongfu New Materials Co., Ltd. and Changzhou Fuxin Technology Co., Ltd. are leading the development and production of graphene thermal materials, focusing on advanced applications in AI, 5G, and automotive sectors [17][21]. - Guangdong Morion Technology Co., Ltd. has established itself as a pioneer in the full-chain production of graphene materials, achieving significant advancements in thermal interface materials [24][25].
