Abstract
The present disclosure describes tunable methods of treating cellulosic materials with a composition that provides increased hydrophobicity and/or lipophobicity to such materials without sacrificing the biodegradability thereof. The methods as disclosed provide for binding of saccharide fatty acid esters on cellulosic materials, including that the disclosure provides products made by such methods. The materials thus treated display higher hydrophobicity, lipophobicity, barrier function, and mechanical properties, and may be used in any application where such features are desired.
Claims17
A method for providing water resistance or water and lipid resistance to a substrate, the method comprising:
- a) preparing a formulation for imparting a water barrier function or a water and lipid barrier function to a substrate, the formulation consisting essentially of a saccharide fatty acid ester and a binder;
- b) coating a surface of the substrate with the formulation;
- and
- c) exposing the coated substrate to heat, radiation, a catalyst, or a combination thereof to bind the saccharide fatty acid ester and the binder to the surface of the substrate,
- wherein the substrate obtained in step c) exhibits a water contact angle greater than 90°.
