Cellulose acetate hollow fiber membrane from banana stem fibers coated by TiO2 (CAHFMT) was prepared and characterized as an alternative material for degradation of waste textile dye. Its applicability was demonstrated by mechanical properties, FTIR, SEM, thermal resistance, performance, and degradation efficiency. Cellulose acetate (CA) was synthesized from banana stem fibers by swelling stage, acetylation reaction, and hydrolysis reaction. CA was modified using TiO2 of various concentrations. CAHFMT with 22 % w/v dope concentration has the optimum mechanical properties (stress, strain and Young’s modulus), as well as hydrophilic properties. The performances of CAHFMT with Congo red were determined. The SEM results showed that the membrane had rigid pores. Moreover, this research stated that CAHFMT could be a solution to overcome economical and effective problems.

Polysulfone/Ru nanocluster hybrid hollow fiber membranes with different Ru content were fabricated by the dry/wet spinning process. The structures and properties of Ru nanocluster, PSF hollow films and PSF/Ru hybrid hollow fiber films were characterized by TEM, SEM, XPS, XRD, TGA, etc. The results showed that the Ru particles, which may coordinate with O and S in polysulfone, distributed symmetrically with an average diameter about 1~2 nm. More finger-like pores of the hybrid membranes were obtained after adding Ru nanocluster, and the thermal properties of the membranes increased while the mechanical properties decreased.
