Production of nanowebs by an electrostatic spinning apparatus and method

United States Patent Application

View the Complete Application at the US Patent & Trademark Office
A method for producing a webbed fibrillar material includes providing a polymer material including a solvent; injecting the polymer material into an electric field toward an electrically charged target; controlling at least one process parameter to produce the webbed fibrillar material having one or more desired characteristics; and collecting the webbed fibrillar material from the target. The process parameter may be selected from the group consisting of an electric field strength, a temperature, a solution viscosity of the polymer material, a distance between an injection point and the target, a solvent type, a relative concentration of the solvent and polymer material, a molecular weight of the molecules of the polymer material, an environmental temperature, an environmental humidity, and a drying time of the injected polymer material.
