Abstract
Przedmiotem zgłoszenia jest sposób otrzymywania roztworu błonotwórczego, polegający na tym, że nanorurki tytanianowe dysperguje się w N,N-dimetyloformamidzie z zastosowaniem ultradźwięków, po czym otrzymaną zawiesinę łączy się z polieterosulfonem, a powstały roztwór poddaje mieszaniu. Sposób ten charakteryzuje się tym, że ultradźwięki podczas dyspergowania nanorurek w N,N-dimetyloformamidzie stosuje się przez 0,5 - 5,0 godzin, po czym dyspersję miesza się z roztworem polieterosulfonu w N,N-dimetyloformamidzie w temperaturze 20 - 25°C z prędkością 200 obr/minutę przez 2 godziny. Tak otrzymany roztwór błonotwórczy pozostawia się do odgazowania. Polieterosulfon stosuje się w ilości 15% masowych. Stosuje się nanorurki tytanianowe w ilości 1% masowych w stosunku do polieterosulfonu, otrzymane metodą hydrotermalną, o średnicy wewnętrznej/zewnętrznej w zakresie, odpowiednio, od 4 nm do 8,3 nm oraz od 8 nm do 13 nm, oraz długości w zakresie od 74 do 164 nm. Do wytwarzania ultradźwięków stosuje się urządzenia o mocy 130 - 320 W, częstotliwości 20 - 40 kHz i amplitudzie 40 - 80%.The subject of the application is a method for obtaining a film-forming solution, in which titanate nanotubes are dispersed in N, N-dimethylformamide using ultrasound, after which the obtained suspension is combined with polyethersulfone and the resulting solution is mixed. This method is characterized in that ultrasound during dispersion of nanotubes in N, N-dimethylformamide is used for 0.5-5.0 hours, after which the dispersion is mixed with a solution of polyethersulfone in N, N-dimethylformamide at a temperature of 20-25 ° C at 200 rpm for 2 hours. The film-forming solution thus obtained is allowed to degass. Polyethersulfone is used in an amount of 15% by mass. Titanate nanotubes are used in an amount of 1% by mass in relation to polyethersulfone, obtained by the hydrothermal method, with an internal / external diameter in the range from 4 nm to 8.3 nm and from 8 nm to 13 nm, respectively, and a length in the range from 74 up to 164 nm. For the production of ultrasound, devices with a power of 130 - 320 W, a frequency of 20 - 40 kHz and an amplitude of 40 - 80% are used.
