| 英文摘要 | Current membrane distillation (MD) is challenged by the inefficiency of water thermal separation from dissolved solutes, controlled by membrane porosity and thermal conductivity. Existing petroleum-derived polymeric membranes face major development barriers. Here, we demonstrate a first robust MD membrane directly fabricated from sustainable woodmaterial. The hydrophobic nanowoodmembrane had high porosity (89 +/- 3%) and hierarchical pore structure with a wide pore size distribution of crystalline cellulose nanofibrils and xylem vessels and lumina (channels) that facilitate water vapor transportation. The thermal conductivity was extremely low in the transverse direction, which reduces conductive heat transport. However, high thermal conductivity along the fiber enables efficient thermal dissipation along the axial direction. As a result, the membrane demonstrated excellent intrinsic vapor permeability (1.44 +/- 0.09 kg m(-1) K-1 s(-1) Pa-1) and thermal efficiency (similar to 70% at 60 degrees C). The properties of thermal efficiency, water flux, scalability, and sustainability make nanowood highly desirable for MD applications. |
