Environmentally Friendly Waterproof and Breathable Nanofiber Membranes with Thermal Regulation Performance by One-Step Electrospinning

Environmentally Friendly Waterproof and Breathable Nanofiber Membranes with Thermal Regulation... The waterproof and moisture permeable fabric with thermal regulation not only has the protective function for human body, but also meets the comfort of human clothing, which is a challenging and innovative research. Herein, we report an environmentally friendly, simple, and high-efficiency strategy to fabricate waterproof and breathable nanofiber membranes with outstanding thermal regulation ability by introducing stearic acid (SA) into the hydrophobic siliceous polyurethane (SIPU) solution by a facile one-step electrospinning. Owing to the addition of SA, the waterproofness of SIPU/SA nanofiber membranes is greatly improved, meanwhile, the addition of SA acted as a phase change material to impart temperature regulation performance in appropriate temperature range to the SIPU/SA nanofiber membranes. By adjusting the addition amount of the SA, eco-friendly and multifunctional SIPU/SA nanofiber membranes are systemically optimized with good waterproofness (79 kPa), moisture breathability (8.0 kg m−2 d−1), and outstanding temperature regulation performance (latent heat up to 40 J/g), satisfied tensile strength (6.2 MPa) and excellent breaking elongation of 182 %. The obtained SIPU/SA nanofiber membranes can be suitable for the design of multifunctional wearable textiles for various applications, especially in outdoor protective clothing, medical clothing, intelligent clothing and military products. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Fibers and Polymers Springer Journals

Abstract

The waterproof and moisture permeable fabric with thermal regulation not only has the protective function for human body, but also meets the comfort of human clothing, which is a challenging and innovative research. Herein, we report an environmentally friendly, simple, and high-efficiency strategy to fabricate waterproof and breathable nanofiber membranes with outstanding thermal regulation ability by introducing stearic acid (SA) into the hydrophobic siliceous polyurethane (SIPU) solution by a facile one-step electrospinning. Owing to the addition of SA, the waterproofness of SIPU/SA nanofiber membranes is greatly improved, meanwhile, the addition of SA acted as a phase change material to impart temperature regulation performance in appropriate temperature range to the SIPU/SA nanofiber membranes. By adjusting the addition amount of the SA, eco-friendly and multifunctional SIPU/SA nanofiber membranes are systemically optimized with good waterproofness (79 kPa), moisture breathability (8.0 kg m−2 d−1), and outstanding temperature regulation performance (latent heat up to 40 J/g), satisfied tensile strength (6.2 MPa) and excellent breaking elongation of 182 %. The obtained SIPU/SA nanofiber membranes can be suitable for the design of multifunctional wearable textiles for various applications, especially in outdoor protective clothing, medical clothing, intelligent clothing and military products.
