Abstract

Przedmiotem zgłoszenia jest sposób otrzymywania cienkościennych pianek węglowych ze związków organicznych. Sposób ten charakteryzuje się tym, że L-histydynę mieszana z węglanami metali alkalicznych albo metali ziem alkalicznych rozdrobnionych do ziaren o rozmiarach nanometrycznych w zakresie od 10 nm do 50 nm w stosunku wagowym L-histydyna : węglan od 2:1 do 4:1 w przeliczeniu na suchą masę, a następnie homogenizuje mechanicznie z dodatkiem wody w proporcji od 1 do 2 w stosunku do suchej masy, a uzyskana masa ogrzewa się z szybkością od 5°C/min do 15°C/min w atmosferze gazu obojętnego do temperatury od 600°C do 900°C i utrzymuje na tym poziomie przez okres od 60 minut do 150 minut, po czym schładza się otrzymaną masę do temperatury około 50°C utrzymując atmosferę beztlenową, po czym uzyskaną masę węglową poddaje się działaniu mocnego kwasu nieorganicznego w celu usunięcia składnika nieorganicznego, a następnie wytrawiony kwasem produkt odmywa się wodą, korzystnie wodą destylowaną do uzyskania wartości pH odcieku w zakresie od 6 do 7, po czym suszy przez okres od 12 godzin do 24 godzin w temperaturze od 100°C do 110°C.The subject of the application is a method of obtaining thin-walled carbon foams from organic compounds. The method is characterized in that L-histidine mixed with alkali metal or alkaline earth metal carbonates ground to nanometric grain sizes ranging from 10 nm to 50 nm in a weight ratio of L-histidine: carbonate from 2: 1 to 4: 1 in calculated as dry mass, and then mechanically homogenized with the addition of water in a proportion of 1 to 2 in relation to the dry mass, and the obtained mass is heated at a rate of 5 ° C / min to 15 ° C / min in an inert gas atmosphere to a temperature of 600 ° C to 900 ° C and held at this level for a period of 60 minutes to 150 minutes, after which the resulting mass is cooled to a temperature of about 50 ° C maintaining an anaerobic atmosphere, and the resulting carbon mass is treated with a strong inorganic acid to removing the inorganic component, and then the acid-etched product is washed with water, preferably distilled water, until the effluent reaches a pH of 6 to 7, and then dried for 12 to 24 hours at temperatures from 100 ° C to 110 ° C.
