Graphene hollow fiber is a new type of functional fiber that combines the excellent properties of graphene and the advantages of hollow fiber structure. With its multiple properties such as electrical conductivity, thermal conductivity, antibacterial, lightweight, and warmth retention, it has been applied on a large scale in many fields. Compared with traditional fibers, its unique structure and performance combination form obvious differentiated advantages, especially its use in specific items, making it a key material to promote industrial upgrading. The following will provide a detailed analysis of its application fields, differences from other fibers and core adaptable items.

The applications of graphene hollow fibers cover many core fields such as textiles, electronics, medical care, environmental protection, aerospace, etc. In the textile field, it is used in smart clothing, thermal underwear, sports equipment, etc., relying on its conductive, thermal and thermal properties; in the electronic field, it is suitable for flexible sensors and wearable electronic equipment electrode materials with the help of its excellent conductivity; in the medical field, it is used in antibacterial dressings and medical protective equipment due to its antibacterial properties and biocompatibility; in the environmental protection field, it is used as sewage purification filter materials by virtue of its high specific surface area and adsorption properties; in the aerospace field, it is used as lightweight structural materials for spacecrafts, relying on its lightweight and high-strength properties.

Compared with traditional fibers and ordinary functional fibers, the differences of graphene hollow fibers are mainly reflected in three aspects. The first is the difference in raw materials and structure: graphene or graphene composite materials are used as the core components, and are combined with polyester, nylon and other base materials to form a hollow structure, while ordinary fibers are mostly solid or simple hollow structures of a single raw material; the second is the difference in core performance: they have the electrical conductivity, thermal conductivity, antibacterial, anti-ultraviolet and other functions of graphene, and the lightweight, warm and breathable properties of hollow fibers. , most ordinary fibers only have basic mechanics or a single function (such as only warmth, only antibacterial); the third is the difference in functional diversity: precise performance control can be achieved by adjusting the graphene content to adapt to multiple scenarios. Ordinary fibers have a single function and are difficult to take into account multiple properties. At the same time, their mechanical properties are better, and their breaking strength is 20%-40% higher than ordinary hollow fibers.

Specifically, graphene hollow fibers can be widely used in various functional items:

• textiles include smart temperature-controlled clothing, antibacterial socks, anti-UV sunshades, and high-end down jacket liners;
• electronics include flexible electronic skin, electrode wires for wearable health monitoring equipment, and flexible battery separators;
• medical include antibacterial medical gauze, wound dressings, and disposable antibacterial protective clothing;
• environmental protection includes heavy metal sewage filter membranes, air purification filters;
• in addition, it can also be used in aerospace lightweight components, new energy vehicle battery thermal conductive materials, etc.

Among them, it is most prominently used in smart wearables and high-end textile items. With the rise of the smart wearable industry, its conductive + flexible + lightweight properties have become the core material of smart clothing, and its usage in products such as heart rate monitoring clothing and temperature-controlled fitness clothing is increasing year by year. In the field of high-end thermal clothing, its hollow structure locks still air to achieve efficient warmth retention, and is superimposed with antibacterial and anti-odor functions. It has become the preferred material for the lining of high-end down jackets and ski suits, and its market penetration rate has increased rapidly. In addition, in the field of medical antibacterial consumables, because it can effectively inhibit the growth of bacteria and improve the level of protection, the proportion of use in special dressings and epidemic protection materials in tertiary hospitals is also significantly higher than that of ordinary fibers.

In summary, graphene hollow fibers have extensive application potential in many fields with their multiple excellent properties. Their differentiated advantages from traditional fibers make them a core material in smart wearables, high-end textiles, medical antibacterial and other items. In the future, as the technology matures and costs are optimized, its application scenarios will be further expanded to provide support for the high-end upgrades of multiple industries.
