Abstract:

The biodegradable superhydrophobic cellulose sheets were fabricated by simple dissolution, controllable crystallization, coagulation, and Teflon dip-coat. The surface morphology of the superhydrophobic regenerated cellulose sheets is similar to that of the natural lotus leaves consisting of hierarchical micro/nano structures. The prepared cellulose sheets exhibit a remarkable superhydrophobicity and satisfactory long-term chemical stability.

Key words: Superhydrophobic cellulose sheet, Hierarchical structure, Regenerated, Biodegradable, Chemical stability
