Abstract
The present invention describes methods of treating cellulosic materials with a composition that provides increased hydrophobicity to such materials without sacrificing the biodegradability thereof. The methods as disclosed provide for esterification of available hydroxyl groups on cellulosic materials, where such hydroxyl groups are “masked” by bulky organic chains, including that the disclosure provides products made by such methods. The materials thus treated display higher hydrophobicity, barrier function, and mechanical properties, and may be used in any application where such features are desired.
