Ca bază a materialului foarte rezistent, care poate fi utilizat în multe domenii, cercetătorii de la Institutul Regal de Tehnologie au folosit nanofibre pe bază de celuloză, informează Rador.
Prelucrarea materialelor naturale la nivel nano a permis oamenilor de ştiinţă să modifice complet structura primară a mai multor tipuri de substanţe şi să facă un fel de selecţie chimică. Rezultatul combină caracteristicile diferitelor materiale. Dacă nanoceluloza prelucrată este amestecată cu substanţele chimice tradiţionale, pot fi obţinute materiale compozite deosebit de puternice. Versatilitatea lor va ajuta ca acestea să fie folosite în practică pentru absolut orice – de la realizarea de biciclete până la aeronave.
