Abstract
The invention relates to a process for preparing individual cellulose nanocrystals having an electrically conductive coating, said process comprising the steps: reacting non-oxidised glucose units of cellulose with an aryl or heteroaryl compound having an isocyanate group to form a carbamate bond between at least one of the C2, C3 and C6 atoms of the glucose unit and the aryl or heteroaryl compound; polymerising adjacent aryl or heteroaryl compounds bonded to the glucose unit of the cellulose via the carbamate group, such that an electrically conductive structure of these compounds containing aryl or heteroaryl groups is formed.
