Abstract: Disclosed are films and materials comprising poly(alkylene glycol)-chitosan and/or chitin-poly(glucuronic acid) and chitosan and/or chitin-poly(glucuronic acid). Methods of making such films, particularly involving thermally crosslinking poly(glucuronic acid) with chitosan, are disclosed.

Abstract: Methods of making various capillary foams are provided. The foams can include liquid foams having a plurality of particles connected by a network of a secondary fluid at the interface between the discontinuous and continuous phase. The foams can also include solid foams where the continuous phases (bulk fluid) is removed to produce the solid foam having high overall porosities and low densities. Densities as low as 0.3 g cm?3 and porosities as high as 95% or higher can be achieved. The secondary fluid can be polymerized to further strengthen the solid foam. Methods and devices are also provided for oil recovery from water using a capillary foam. The methods can include forming a capillary foam wherein the oil is the secondary fluid, and wherein the foam can transport the oil to the surface of the water.

Abstract: Embodiments of the present disclosure provide for compositions and methods of making a waterborne epoxide resin that contains cellulose nanocrystals or nanofibrils.

Abstract: Embodiments of the present disclosure provide compositions, structures such as films and foams, methods of making nonaggregated stabilized charged polysaccharide nanofibers (e.g., nonaggregated stabilized cationized chitin nanofibers), methods of making structures such as films and foams, and the like.

Abstract: The invention relates to composite blend membranes formed from blends of one or more polyelectrolytes, and one or more types of nanoparticles. Preferably the blend also includes one or more fluoropolymers. The addition of the nanoparticles was found to enhance the conductivity and mechanical properties of the membranes.
