High-Performance Wigs via the Langmuir–Blodgett Deposition of Keratin/Graphene Oxide Nanocomposite

Wigs provide a common service as hair accessories in people's daily life. However, the traditional wigs, regardless of the matrices derived from human hair or synthetic fibers, are faced with limitations such as short service life, dry and brittle texture, and static electricity. In this work, we described a new strategy for surface coating of wigs via the Langmuir-Blodgett (LB) technique using a nanocomposite composed of hair-derived keratin and graphene oxide (Ker/GO). In contrast to the conventionally used immersion method, this strategy achieved a significantly higher surface coverage with a close-packed structure and controlled deposition layers of the coating, thus delivering high performances, including greatly enhanced ultraviolet (UV) resistance, antistatic electricity, heat dissipation, hydroscopicity, and moisturizing ability, and durability against washing, for both the human hair and synthetic-fiber-based wigs.
