摘要： The present disclosure describes methods of treating fibrous cellulosic materials with sucrose fatty acid ester containing particles (carrier systems) that allow for modifications of surfaces, including making such surfaces water resistance and/or oil/grease resistance. The methods as disclosed provide combining at least one saccharide fatty acid esters (SFAE) with a polymer (e.g., latexes) to form micellular particles and applying such particles to substrates including fibrous cellulose-based materials (e.g., pulp) to form, inter alia, molded products. Compositions comprising combinations of SFAE, a latex and optionally a mineral or other additives are also disclosed.

摘要： The present disclosure describes acyl halide liquid dispersions and tunable methods of treating cellulosic materials with compositions that provide increased hydrophobicity and/or lipophobicity to such materials without sacrificing the biodegradability thereof. The methods as disclosed provide for reacting acyl halides with and 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.

摘要： The present disclosure describes a method to modify dried polymer films using printed crosslinking agents, including that the crosslinked polymer resulting from the method exhibits greater insolubility compared to crosslinked polymers made where the crosslinking agent and the polymer are combined and applied as a homogenous solution. Articles of manufacture generated by such a method are also disclosed.
