Electrospun Nanofibers from PUR and PVDF Embedded with SiO2 Aerogel for Advanced Thermal Properties

Popis výsledku v původním jazyce

Textiles protect humans from extreme climatic conditions. The efficacy of the fabric is important for performance under extreme conditions. Different fabrics and coating materials need to be studied to improve the thermal properties of textiles. The thermal properties of nanofibers and their potential protection against cold environments are relatively unknown. Thermal insulation battings incorporating nanofibers could possibly decrease the weight and bulk of current thermal protective clothing, and increase mobility for soldiers in the battlefield. In this work, we addressed the mechanisms of heat transfer through fibrous insulation where the fiber diameter is less than 1 micrometer (μm). Flexible electrospun nanofibre embedded with silica aerogel was produced via electrospinning process. The electrospun PUR and PVDF nanofibers was embedded with SiO2 aerogel. The effects of thermal properties of the electrospun nanofibre embedded with SiO2 aerogel were analyzed. The microscopic examination confirmed presence of aerogel particles. The results were statistically analyzed. They showed enhancement of thermal insulation by increasing the number and the weight per unit area of both nanofibrous layers. The results also confirmed that embedding silica aerogel in nanofibrous layers leads increased thermal insulation. Based on the results, it could be concluded that nanofibers are useful for thermal insulation.
