Latest Patents
Radka D Yankova holds a patent for a method for the production of membrane battery separators. This improved method involves grafting a vinyl monomer onto a polyolefin film. The process includes the irradiation of the film using ultraviolet rays and subsequent grafting in a five-layer sandwich configuration. The sandwich consists of an irradiated polyolefin film, which is covered on each side with a layer of cellulosic tissue soaked in the monomer or a solution of the monomer. Each cellulosic layer is further covered by an inert polymeric film. The layers are not limited in length, and the sandwich is transported at a constant speed over a heater surface, maintaining a temperature range of 85 to 95 degrees Celsius with precise accuracy. The grafting process occurs continuously and isothermally while in contact with the heater surface under a pressure of 10 to 30 g/cm² for a duration of 10 to 45 minutes.
