Atom numbering in monomer units of polyacrylamide (PAM) (a) and a cellulose nanocrystal (CNC) (b), CNC with a predominantly hydrophobic surface (c—top view; d,e—end-on views) and with a predominantly hydrophilic surface (f—top view; g,h—end-on views). The red spheres denote the oxygen atoms, the gray ones represent the hydrogen atoms, the cyan ones show the carbon atoms, and the blue sphere represents the nitrogen atom. The instant snapshot of System 3 (i): CNC is blue and PAM macromolecules are green, the red dots are the water molecules.
