Membrane distillation (MD) for water treatment can be applied in high salinity conditions and of wastewater. Current commercial membranes are made fluorinated polymers such as polytetrafluoroethylene (PTFE). Here, porous were coated with a silicone nanofilament layer to obtain superhydrophobic fluorine-free material. The classical coating procedure involves the use toluene solvent. In this work, n-heptane was tested less toxic alternative. Different substrates coating. effect acids, scaling solutions, biofilm formation analyzed comparison standard PTFE membranes. We demonstrate that nanofilament-coated poly(ether sulfone) (NF-PES) possess required antiwetting properties MD. Moreover, NF-PES have static contact angles between 10 20° higher than after immersion tests solutions containing substances, grows from 20 50%, PTFE.
