Abstract
Correction for ‘Cationic surface functionalization of cellulose nanocrystals’ by Merima Hasani et al., Soft Matter, 2008, 4, 2238–2244.
In our paper the statement on p. 2240, under desulfation procedure, that the sulfate ester groups were “removed completely by hydrolysis to functionalization…” is unjustified. This statement was based on a titrimetric method, but the sulfate ester group may not have been converted to acid-form prior to titration, as required for valid results. The extent of desulfation is thus not known. The main results and conclusions regarding the cationic surface functionalization of cellulose nanocrystals are unaffected.
The Royal Society of Chemistry apologises for these errors and any consequent inconvenience to authors and readers.
