Supporting data for "Unveiling the growth of polyamide films for enhanced selectivity and applying a highly selective polyamide nanofilm for energy harvesting from acid mine drainage"

This dataset concludes the characterization of polyamide nanofilms, including SEM, TEM, AFM, QCM, XPS, WCA, and DBES. The performance tests include water permeance, salt rejection (e.g., Na2SO4, MgSO4, MgCl2, NaCl), neutral molecular rejection (e.g., boron, As (III), and micropollutants), anti-fouling test, and energy output performance (open circuit voltage and power density).
