摘要： Polymeric materials are provided that are produced from a blend of hydrophilic and hydrophobic biodegradable polymers. The polymeric materials can form fibers, nonwoven fabrics, films, coatings, etc. A compound can be incorporated in the polymeric materials. The delivery of the compound can be controlled by diffusion of the compound from the polymeric material and during biodegradation of the polymeric material. The release rate is controlled by varying the composition of the polymeric material to control diffusion rates of the compound and/or biodegradation rate of the polymeric material. This technology provides methods for delivering and controlling release rates of pesticides and related compounds in agricultural and non-agricultural settings. When adhered to plants or plant parts, the polymeric materials can provide protection from insect and disease pests. In pellet or capsule form, pesticides can be delivered into seed furrows along with crop seeds, providing similar protection.

摘要： The present invention relates generally to compositions for use in biological and chemical separations, as well as other applications. More specifically, the present invention relates to hybrid felts fabricated from electrospun nanofibers with high permeance and high capacity. Such hybrid felts utilize derivatized cellulose, and at least one non-cellulose-based polymer that may be removed from the felt by subjecting it to moderately elevated temperatures and/or solvents capable of dissolving the non-cellulose-based polymer to leave behind a porous nanofiber felt having more uniform pore sizes and other enhanced properties when compared to single component nanofiber felts.

摘要： A gradient nanofiber non-woven contains a plurality of nanofibers where at least 70% of the nanofibers are bonded to other nanofibers. The nanofibers each have a surface and a center and contain a bulk polymer and a third component. The majority by weight at the surface of the nanofiber is the third component and the majority by weight at the center of the nanofiber is the bulk polymer and there is a concentration gradient from most concentrated to least from the surface of the nanofiber to the center of the nanofiber. The process for forming a gradient nanofiber non-woven is also disclosed.
