靜電紡絲

Electrospinning is a technique used to produce nanofibers by applying a high-voltage electric field to a polymer solution, creating thin fibers as the solution is drawn out.

Thermal Insulation: Achieving Gas-Like Insulation with ZrO₂/SiO₂ Nanofiber Aerogels

Thermal insulation is a critical requirement in various engineering applications, especially for high-temperature environments. One innovative approach involves the creation of aerogels from ZrO₂/SiO₂ nanofibers, which can achieve insulation properties similar to those of gases. These nanofiber-based aerogels exhibit ultra-low thermal conductivity, making them highly effective as insulators. The unique porous structure traps air within the aerogel, minimizing heat transfer and providing exceptional thermal resistance, making it ideal for applications where lightweight and efficient insulation is required.

The combination of ZrO₂ and SiO₂ nanofibers forms a robust yet lightweight aerogel structure that leverages the thermal stability of ZrO₂ and the flexibility of SiO₂. This composite material demonstrates excellent resistance to heat while maintaining structural integrity, allowing it to serve as a highly effective thermal barrier in various industrial and aerospace applications.

Radiative Cooling: Energy-Free Cooling with PS/PVDF Nanofiber Films

Radiative cooling is an innovative cooling method that dissipates heat by emitting infrared radiation without consuming energy. Using nanofiber films made from polystyrene (PS) and polyvinylidene fluoride (PVDF), researchers have developed a passive cooling solution that lowers temperatures effectively. These nanofiber films are designed to emit thermal radiation while reflecting sunlight, which helps maintain cooler temperatures without the need for electricity or active cooling systems.
