A novel TFC NF membrane was prepared on a polyacrylonitrile (PAN) supporting film using interfacial polymerization with the 3,3′,5,5′-biphenyl tetraacyl chloride (mm-BTEC) monomer and piperazine (PIP). In the interfacial polymerization process, organic solvents were changed from cyclohexane to toluene, which increased the diffusion rate and solubility of PIP in the organic solvent. The diffusion of...
