From: Rapid mold-free fabrication of long functional PDMS fibers
a Schematic illustration of the porous PDMS fiber fabrication process to achieve thermal insulating properties. b FE-SEM image, c width and thickness, d porosity and density, and e mechanical properties of the porous PDMS fibers according to the PMMA contents. Comparison of the thermal insulation properties of general polyester fabric, the PDMS film, and six fabrics based on the porous PDMS fibers (PPF-1, 2, 3, 4 (one layer), 4 (two layers), and 4 (three layers)) illustrated as f IR images during heating at 100 °C and g after 60 min of cooling at –15 °C. h Temperature of the fabric surface after 60 min under different temperature conditions from –20 to 100 °C.
