Cellulose-inorganic hybrids of strongly reduced thermal conductivity

Abstract The employment of atomic layer deposition and spin coating techniques for preparing inorganic–organic hybrid multilayer structures alternating ZnO-CNC layers was explored in this study. Helium ion microscopy X-ray reflectivity showed the superlattice formation nanolaminate force established efficient control CNCs surface coverage on Al-doped ΖnO by manipulating concentration solution. Thickness characterization performed via both ellipsometry thermal conductivity examined time domain thermoreflectance technique. It appears that even incorporation a limited amount between ZnO laminates strongly suppresses conductivity. Even small, submonolayer amounts worked as more insulating material than hydroquinone or cellulose nanofibers which have been employed previous studies.
