Positron annihilation lifetime spectroscopy (PALS) and molecular dynamics (MD) simulation analyses were adopted for an in-depth understanding at the molecular scale of the variation in the fine-structure of polyamide active layers of thin-film composite (TFC) membranes in the dry or the wet condition. The interfacial polymerization reaction between 1,3-diaminopropane (DAPE) and succinyl chloride (SCC) or between DAPE and trans-3,6-endomethylene-1,2,3,6-tetrahydrophthaloyl chloride (tNBDC) on the surface of a modified polyacrylonitrile (mPAN) membrane was carried out to fabricate DAPE-SCC/mPAN or DAPE-tNBDC/mPAN TFC membranes. PALS and MD simulation experimental results were highly consistent with each other. (C) 2012 Elsevier B.V. All rights reserved.
