Abstract:
Celuloza, ki je glavni gradnik celičnih sten v rastlinah, zaradi svoje biorazgradljivosti in obnovljivosti vedno bolj pridobiva pozornost na novih področjih uporabe kot je nanotehnologija. Znanstveniki s pomočjo kislinske hidrolize pridobivajo celulozne nanokristale, ki s svojimi edinstvenimi lastnostmi predstavljajo odličen material za utrjevanje kompozitov, prav tako pa imajo potencial v drugih področjih uporabe. Cilj te diplomske naloge je bil pridobitev celuloznih nanokristalov z uporabo žveplove (VI), fosforne (V), ter klorovodikove kisline. Kot vir celuloze sem uporabila odpadni bombaž iz predilnice Litija. Optimizirala sem pogoje hidrolize pri različnih kislinah ter analizirala dobljene nanokristale.

Title:
Isolation of cellulose nanocrystals with different acids
Abstract:
Cellulose, the main component of cell walls in plants, is because of its biodegradability and renewability getting more attention in new areas of use such as nanotechnology. Scientists are using acid hydrolysis for producing cellulose nanocrystals, that make with their unique properties an excellent material for reinforcing composites and are showing the potential for other applications. The goal of this work was to extract cellulose nanocrystals, using sulfuric (VI), phosphoric (V) and hydrochloric acid. The source of cellulose was waste cotton from Litija Spinnery. I optimized the hydrolysis conditions for different acids, and analyzed the extracted nanocrystals.
