•Origin of chiral interactions between cellulose macromolecules has been addressed.•Two concepts to explain these chiral interactions have been presented.•Experimental evidence to show twists in cellulose microfibril has been presented.•Protein aggregation theory has been used in context of cellulose.
The formation of a chiral-nematic phase from cellulose nanowhiskers has been frequently reported in the literature. The most popular theory used to explain the chiral interactions is that of twisted morphology of cellulose nanowhiskers. Two possible origins of twist have been suggested: the intrinsic chirality of cellulose chains and result of interaction of chiral surfaces. High resolution SEM and AFM have been used to locate twists in cellulose microfibrils and nanowhiskers. The origin of the twisted morphology in cellulose microfibrils has been studied with reference to the protein aggregation theory.
