Abstract
Przedmiotem zgłoszenia jest sposób selektywnej izolacji półprzewodnikowych, jednościennych nanorurek węglowych, który polega na tym, że do 1 mg do 5 mg nanorurek węglowych, korzystnie 1,5 mg, dodaje się od 4 mg do 35 mg polimeru przewodzącego o masie cząsteczkowej od 9 kg/mol do 45 kg/mol i wagowej od 26 kg/mol do 128 kg/mol, przy czym stosunek wagowy polimeru do nanorurek węglowych wynosi od 4:1 do 8:1, korzystnie 5:1 do 7:1, następnie rozpuszcza się w 2,65 ml na każdy 1 mg nanorurek węglowych rozpuszczalnika organicznego lub mieszaniny rozpuszczalników organicznych, korzystnie 4 ml, tak przygotowaną heterogeniczną mieszaninę poddaje się wstępnej sonikacji, przy czym proces prowadzi się w temperaturze od 0°C do 60°C, korzystnie nie wyższej niż z 10°C z wykorzystaniem łaźni ultradźwiękowej o mocy powyżej 200 W — 1000 W, w czasie od 5 minut do 24 h, otrzymaną zawiesinę homogenizuje się homogenizatorem ultradźwiękowym z sonotrodą w temperaturze od 0°C do 60°C, korzystnie nie wyższej niż 10°C w czasie 5 min do 30 minut, odwirowuje z względną siłą wirowania RCF co najmniej min. 6000 x g, w czasie od 3 min do 10 minut z mocą od 2,5 W do 4 W na ml zawiesiny.The subject of the application is a method of selective isolation of semiconductor, single-wall carbon nanotubes, which consists in adding from 4 mg to 35 mg of a conductive polymer with a molecular weight of 9 kg/ mol to 45 kg/mol and weight from 26 kg/mol to 128 kg/mol, where the weight ratio of polymer to carbon nanotubes is from 4:1 to 8:1, preferably 5:1 to 7:1, then dissolved in 2.65 ml for each 1 mg of carbon nanotubes of an organic solvent or a mixture of organic solvents, preferably 4 ml, the heterogeneous mixture prepared in this way is subjected to preliminary sonication, and the process is carried out at a temperature from 0°C to 60°C, preferably not higher than at 10°C using an ultrasonic bath with a power above 200 W - 1000 W, for 5 minutes to 24 h, the obtained suspension is homogenized with an ultrasonic homogenizer with a sonotrode at a temperature from 0°C to 60°C, preferably not higher than 10 °C for 5 min to 30 min, centrifuged with a relative centrifugation force RCF of at least min. 6000 x g, for 3 min to 10 minutes with a power of 2.5 W to 4 W per ml of suspension.
