Abstract:
The paper describes the separation of an oil–water emulsion by filtration using poly(ethylene
terephthalate) track-etched membranes (PET TeMs) with regular pore geometry and narrow pore
size distribution. PET TeMs were modified with trichloro(octyl)silane to increase their hydrophobic
properties. Conditions for the modification of PET TeMs with trichloro(octyl)silane were investigated.
The results of changes in the pore diameters and the contact angle depend on the concentration of
trichloro(octyl)silane and the soaking time are presented. The obtained samples were characterized
by FTIR, AFM, SEM-EDX and gas-permeability test. Chloroform–water and cetane–water emulsions
have been used as a test liquid for oil–water separation.
