Definitions

  • nanoparticulate metal salts provides an improved process which, on the one hand, provides suitable pores in the membrane and on the other hand, provides an improved manufacturing rate. This is unexpected, as the skilled person (i) would not expect the dissolution of nanoparticulate material from a polymer film because nanoparticles are expected to be individually coated by polymer and thus protected from dissolution.
  • Step (f) may be performed using processes known per se.
  • the removal step f ) aims to remove substrate (6) to obtain an unsupported porous material (1) or to transfer the porous material to another supporting material to obtain a coated article.
  • the pores of the material may be arranged in a way that the material is permeable, partly permeable or impermeable. If essentially all pores of the material have dead ends, the material is impermeable. In the contrary, if essentially all pores of the material have open ends, the material is considered permeable. Consequently, if a fraction of the pores has dead ends, the material is considered partly permeable.
  • the present invention provides polymer membranes, wherein at least 90 % of said pores are interconnected.
  • Step b) The dispersion is applied on a substrate (e.g. glass) using spin coating or roll coating and dried afterwards.
  • a heating step can be applied for faster drying of the applied films (evaporation of the solvent; step c) ) .
  • the coating knife has 50 ⁇ slots, forward speed is set to 18mm/s. 1ml of dispersion was used to create a film of approximately 10 x 10cm 2 area. Finally, the salt nanoparticles are dissolved in 1M hydrochloric acid (denoted as HC1) for 3 minutes to reveal the porous structure. The film is then washed in de-ionized water (Millipore, electrical resistivity > 18MQcm) and ethanol and dried on air for 2 hours. d) Porous urea-polydimethylsiloxane membrane (porous urea- PDMS membrane)
