Abstract
Przedmiotem zgłoszenia jest sposób wytwarzania membran z polieterosulfonu modyfikowanych nanorurkami tytanianowymi, metodą inwersji faz - wariant mokry, z wykorzystaniem N,N-dimetyloformamidu jako rozpuszczalnika, z użyciem ultradźwięków, który charakteryzuje się tym, że nanorurki tytanianowe rozprasza się w N,N-dimetyloformamidzie z dodatkiem dodecylosiarczanu sodu jako środka dyspergującego, otrzymaną zawiesinę łączy się z roztworem polieterosulfonu w N,N-dimetyloformamidzie, a powstały roztwór poddaje mieszaniu na mieszadle magnetycznym, stosując prędkość 300 obr/min przez 2 godziny. Otrzymuje się roztwór błonotwórczy zawierający 15% mas. polieterosulfonu, 80 - 84,5% mas. N,N-dimetyloformamidu, 0,25 - 5% mas. dodecylosiarczanu sodu oraz 0,15% mas. nanorurek tytanianowych, który wylewa się na płytę i zanurza w nierozpuszczalniku uzyskując membranę. Proces wymieszania nanorurek tytanianowych z rozpuszczalnikiem i środkiem dyspergującym prowadzi się przy użyciu łaźni ultradźwiękowej o mocy 320 W, 40 kHz.The subject of the application is a method of producing polyethersulfone membranes modified with titanate nanotubes, by the phase inversion method - wet variant, using N, N-dimethylformamide as a solvent, using ultrasound, which is characterized by the fact that titanate nanotubes are dispersed in N, N-dimethylformamide with by adding sodium dodecyl sulfate as a dispersing agent, the resulting suspension is combined with a solution of polyethersulfone in N, N-dimethylformamide, and the resulting solution is stirred with a magnetic stirrer at a speed of 300 rpm for 2 hours. A film-forming solution containing 15 wt.% Is obtained. polyethersulfone, 80-84.5 wt.% N, N-dimethylformamide, 0.25 - 5 wt.% % sodium dodecyl sulfate and 0.15 wt.%. titanate nanotubes, which are poured onto a plate and immersed in a non-solvent to form a membrane. The process of mixing titanate nanotubes with a solvent and dispersant is carried out using an ultrasonic bath with a power of 320 W, 40 kHz.
