1 Fig. 5 Thermal insulation performance of nanowood in comparison with a silica aerogel, a Styrofoam, and a natural wood. Thermal insulation performance of nanowood in comparison with a silica aerogel, a Styrofoam, and a natural wood. (A) Photograph of a 1-mm-thick specimen of a nanowood. (B) SEM side view of the nanowood channels composed of aligned cellulose nanofibrils. (C) Optical reflection, transmission, and absorption of the silica aerogel and nanowood illuminated by the standard solar simulator. (D) Schematic description of the nanowood being illuminated transversely (perpendicular to the nanofibrils). (E and F) Summary of results showing the stabilized backside temperatures of the thermal insulators when the top surface is in direct contact with a conductive heat source via thermal paste. (G) Schematic description of the measurement setup using radiative heat sources (solar simulator). (H and I) Summary of the results showing the stabilized backside temperatures of each thermal insulator, with the top surface receiving radiative energy from the solar simulator. Tian Li et al.
