摘要:
This invention relates generally to cellulose nanocrystal-based emulsions that can serve as a spray adjuvant for improved agrochemical application efficiency. More particularly, the cellulose nanocrystal-based emulsions are nanocellulose-stabilized Pickering emulsions having a semi-liquid formulation of colloidal cellulose nanocrystals and biopolymers that can substitute currently used surfactants and drift reducing agents in agrochemicals. The cellulose nanocrystal-based emulsions are suitable with both water soluble and oil soluble active ingredient chemistries, and the shear characteristics of the emulsions make them suitable for oil in water-based spray applications. Droplet size distribution can be tuned by changing the ingredient concentrations, thus helping control particle drift. Moreover, a stable cross-linked network formation facilitates the entrapment and encapsulation of volatile agrochemical chemistries, thus preventing their volatilization and reducing vapor drift.

Optically transparent films can comprise a coating of nanodiamonds to introduce desirable properties, such as hardness, good thermal conductivity and an increased dielectric constant. In general, transparent conductive films can be formed with desirable property enhancing nanoparticles included in a transparent conductive layer and/or in a coating layer. Property enhancing nanoparticles can be formed from materials having a large hardness parameter, a large thermal conductivity and/or a large dielectric constant. Suitable polymers are incorporated as a binder in the layers with the property enhancing nanoparticles. The coatings with property enhancing nanoparticles can be solution coated and corresponding solutions are described.
