摘要： Mechanically strong, biodegradable and reusable aerogels are disclosed, which can be made with a cross-linked cellulose ester, and which exhibit a low density and high porosity. The aerogels disclosed herein may be used as sorbent materials and can be modified with a hydrophobic and/or oleophilic agent.

摘要： Suspensions include an aqueous medium and a plurality of particles. The particles include polymeric carrier material dispersed throughout the particle and active ingredient dispersed throughout the particle. The polymeric carrier material can be biodegradable, and one example is a cellulose ester. Exemplary active ingredients include an insecticide, a fungicide, and a pesticide. In some instances, the plurality of particles have an average diameter of 25 nm to 5 μm. Exemplary suspensions may be applied to plant surfaces.

摘要： Aqueous mixtures can include cellulose nanocrystals and sulfonated polyester, where a glass transition temperature (Tg) of the sulfonated polyester is greater than 25° C. In some instances, exemplary aqueous mixtures also include one or more additives, such as pigment. Exemplary aqueous mixtures can be applied as a film that is typically hydrophobic and resilient against water at room temperature. Upon application of warm water, such as at temperatures of from about 30° C. to about 60° C., the film can be removed with no or limited abrasion and/or with no or little removal oils.

摘要： Suspensions can include a polar solvent, sulfonated polyester material dispersed in the polar solvent, and cellulose nanofibril material dispersed in the polar solvent. Suspensions disclosed and contemplated herein leverage polyester that can be used to independently control film formation and rheology. In some instances, polyesters used in suspensions disclosed herein can perform the role of two additives: aqueous thickener and film reinforcement
