Abstract
Invenţia se referă la nanofibre celulozice şi la un procedeu pentru obţinerea acestora. Nanofibrele conform invenţiei sunt sub formă pulverulentă, cu un diametru de 10...60 nm şi factor de formă 10...50, cu un grad de cristalinitate de minimum 80%. Procedeul conform invenţiei constă în tratarea unei dispersii apoase, de concentraţie 20...50%, de sursă celulozică, cu acid sulfuric de concentraţie 95...98%, la început la temperatura camerei, şi apoi la o temperatură de până la 70°C, sub agitare continuă la o viteză de 300...1500 rpm, apoi suspensia de nanofibre celulozice rezultată se spală până laH de minimum 4, şi se usucă prin liofilizare, rezultând nanofibre celulozice uscate.
