Structured nanocelluiose hydrogels, aerogels and thin films were prepared using different techniques and by controlling NFC interactions. Facile functionalization of structured materials of nanofibrillated cellulose with silver nanoparticies were demonstrated. - The NFC-Ag gel was initiated by strong association of carboxylate groups on NFC with Ag* and sufficient NFC surface charge reduction, and stabilized by interfacial hydrogen bonding interactions among nanofibrils. - NFC-Ag aerogels were prepared using two approaches, and structure changes were investigated. - Smooth NFC-Ag thin films were prepared with good optical qualities, and surface nanofribrils showed less coalescence than NFC film.
