As the harmfulness of Ultraviolet rays is widely known, it has become important to protect the skin from ultraviolet rays. UV can cause cancer, wrinkles. Most people choose sunscreens and textiles to protect against UV rays. However, conventional sunscreens have promoting skin disorders due to chemical composition, and short duration. Here, we introduce a novel portable electrospinning system that can coat nanofibrous sunscreen directly onto the skin. nanofibrous sunscreen has suitable structure for UV protection due to its high specific surface area. However, conventional electrospinning systems are not portable, as they include a high voltage power supply that is large in size, heavy in weight. To overcome these limitations, we have developed a one-handed electrospinning system that replaces HVPS with batteries and high-voltage amplifiers. We have confirmed that nanofibers with similar structures to that of conventional electrospinning devices can be fabricated by portable electrospinning system. Nanofibrous sunscreen were fabricated by PU and nanoparticles such as ZnOor TiO2 to increase the UV blocking effect. In addition, we confirmed that UV protection effect, durability and reduced irritation from the physical interception by analyzing ultraviolet transmittance, water resistance, and removal test. Finally, we have successfully developed a portable electrospinning system for the UV blocking.
