Abstract: In this research silica aerogels were incorporated into PVC fabrics by the research team to improve the overall performance of the fabrics. The aerogel was added in percent fractions of 0, 2, 3, and 4%. The thermal conductivity of the resulting samples was measured using the Hot Disk TPS 2500S. Comprehensive analysis of physical and mechanical properties was also performed. Thermal conductivity measurements revealed that the addition of the silica aerogel had reduced the thermal conductivity of the fabric; when 4% silica was added, the thermal conductivity dropped by 26%. As a result of this drop, the new fabric has much higher insulation capabilities. The new fabric was also much lighter, and the authors concluded that it would be a good option in applications such as tents and container linings.
