Physico-Mechanical Study of CMC/BFO/PoPD Nanocomposite Films Reinforced with Cellulose Nanocrystals (CNCMCC) for Effective Photocatalytic Removal of Methyl Orange

The present study was conducted to develop a nanocomposite film of carboxymethyl cellulose (CMC) reinforced with nanocrystals isolated from microcrystalline (CNCMCC) in the presence bismuth ferrite (BFO)/poly-o-phenylenediamine (PoPD). physicochemical properties, mechanical and thermal stability, its photocatalytic activity towards removal methyl orange (MO) were determined. Results show that integration CNCMCC into CMC matrix enhanced strength film. tensile (TS) increased 0.205 0.244 MPa, while elongation at break (EB) decreased 201.44 168.78% 20 wt.% CNCMCC. incorporation substantially nanocomposite’s stability 181.16 185.59 °C degradation residue 72.64 63.16%. determination CMC/CNCMCC/BFO/PoPD composite revealed 93.64% high structural integrity after 3 h treatment. Thus, CNCMCC-reinforced CMC/BFO/PoPD can be used as photocatalyst for organic pollutants wastewater, including orange.
