Preparation and characterization of TiO2/polyethylene nanocomposite membranes

High density polyethylene (HDPE) membranes embedded with TiO2 nanoparticles were fabricated viathermally induced phase separation (TIPS) method. Different structural evaluation tests including FESEM, XRD andAFM were carried out to study the effect of nanoparticles on the structure of membranes. FESEM images showed thatthe membranes had leafy structure indicating solid-liquid phase separation mechanism. The results of XRD analysisconfirmed the presence of TiO2 nanoparticles in the polymer matrix. AFM images showed that the surface roughness ofTiO2 embedded membranes were higher than that of neat HDPE membrane. The performance of membranes was studiedby separation of collagen solution. The results showed that incorporation of nanoparticles slightly increased collagenrejection of membranes
