This study examines the effects of functionalized m-phenylenediamine (m-PDA-f) on structure cellulose acetate (CA) polymeric membranes enhanced with zinc oxide nanoparticles (ZnO). The were prepared by dissolving in an aprotic solvent, followed a phase inversion process. addition m-PDA-f facilitates formation bridges between and ZnO nanoparticles. is confirmed FTIR analysis, which reveals shift wavenumber 3 to 5 cm⁻¹, highlighting increase number hydrogen bonds formed. Thermogravimetric analysis (TGA) confirms stability membranes, significant thermal decomposition temperature: from 235 °C for pure 285 composite containing polymer. Differential scanning calorimetry (DSC) lower enthalpy values where mPDA-f present alongside ZnO. Furthermore, best hydrophilicity was observed CA – exhibiting contact angle 34 degrees water droplets, compared 51 membrane without demonstrates compatibility polymer nanomaterial through additional stable bonds.
