Silica nanofibrous membranes with ultra-softness and enhanced tensile strength for thermal insulation

Abstract

Novel silica nanofibrous membranes with ultra-softness of 40 mN and enhanced tensile strength of 5.5 MPa were prepared for the first time <italic>via</italic> an electrospinning process, which exhibited an ultra-low thermal conductivity of 0.0058 W m⁻¹ K⁻¹.
