Membrane technology has been extensively used for water and wastewater treatment. Hydrophilic polymer
membranes such as cellulose acetate (CA) are good choice for membrane separation process due to moderate
flux and excellent hydrophilicity, which lead to enhance the anti-fouling property. In this study, membranes
were prepared by pristine and polyethylene glycol (PEG) -grafted nanodiamond (ND) embedded in CA as
matrix polymer, and characterized by tensile and antibacterial test. Results shown the improvement in
mechanical and antibacterial property of CA membrane by incorporation of nanoparticles into matrix of CA
membrane.
