Abstract

A biobased cellulosic scaffold material was made through freeze-drying ice-templating of functionalized cellulosic nanomaterials. The resulting interconnected highly porous scaffold was primarily composed of highly esterified, strong network of ultrathin cellulosic layers. The prepared cellulosic scaffold material displayed multifunctional properties of hydrophobicity, oleophilicity and lipophilicity, which could selectively absorb milkfat, hydrophobic proteins, various organic solvents and oils. Diverse potential for the structural and medical applications, such as tissue engineering, drug delivery, and oil and fat accumulation are proposed. (Graph Presented).
