I-N phase transition depends on CNC aspect ratio and length distribution; increase in ionic strength (from 0.3 mM to 3-10 mM) results in a decrease of a nematic phase content; bacterial CNCs form nematic phases at lower concentrations, and are more susceptible to salt-induced gelling; the effect of different counterions is attributed to generation of a repulsive hydration force, which is higher for cations with higher hydration energy (e.g. Li+); an attractive force due to entropy-driven interactions in the presence of quaternary ammonium cations results in a sharper decrease of a nematic phase content
