2.3.5. Transmission Electron Microscopy (TEM)

TEM was used to visualize the shape of the NCC in the original aqueous dispersion. A drop of the aqueous dispersion was placed onto a copper grid with a carbon film and excess liquid was removed using Whatman ® 110 filter paper (Whatman PLC, Maidstone, England), after which the sample was dried at room temperature (22 ◦C) for 24 h. The sample was visualised using a Zeiss Libra ® 120 TEM (Carl Zeiss AG, Munich, Germany).
