    摘要: The invention concerns a method for producing a superhydrophobic membrane or surface coating of a substrate from an aqueous phase comprising the following steps:
    a) Preparing an aqueous dispersion by dispersing particles of hydrophobic polymer(s) in an aqueous solution of protic polymer(s), wherein the protic polymer(s) and the hydrophobic polymer(s) are present in a weight ratio of protic polymer(s) : hydrophobic polymer(s) in a range of 5 : 95 to 22 : 78,
    b) electrospinning the dispersion of step a) onto a carrier for producing the membrane or onto the surface for producing the surface coating thereby producing at least one fiber and a nonwoven fabric from the fiber,
    c) subjecting the nonwoven fabric to a sol-gel process, wherein a precursor/precursors of the sol-gel comprise(s) an alkoxysilane, and
    d) curing the nonwoven fabric obtained by step c) at a temperature in a range of 50°C to 150°C.
