Abstract : Two commercial polyamide (PA) thin film composites with different PA cross-linking densities were examined on
the morphology, chemical structure, Doppler broadening positron annihilation spectroscopy, and salt desalination performance.
The highly cross-linked AG sample resulted in a higher salt rejection but slightly lower water permeance. Meanwhile the
highly cross-linked sample showed a smaller S parameter than the loosely cross-linked one. The interplay between polymer
cross-linking structure, salt rejection behavior, and Doppler broadening annihilation spectra is discussed.
Index Terms - Cross-linked polyamide, Doppler broadening spectra, interfacial polymerization, salt rejection.
