|abstract: ||Superhydrophobic cellulose nanocomposites were prepared using a multi-step nanoengineering process.
The combination of different techniques made it possible to construct novel features at the ensuing surface,
characterized by both an increase in its roughness induced by amorphous silica particles and a
reduction in its energy insured by perfluoro moieties, giving rise to water contact angles approaching
150◦. The modification calls upon an aqueous LbL system followed by siloxane hydrolysis, both conducted
at room temperature in air. Each modification was followed by scanning electron microscopy (SEM) and
atomic force microscope (AFM). These original cellulose–silica–silane composite materials open the way
to further valorisations of a ubiquitous renewable resource in applications such as water repellence and
