摘要：
1. The process of producing highly organic nuclear polytetrafluoroethylene mixed film structure for ultraviolet radiation includes three stages: organic, water and dilute water phase； In the organic phase, an organic solvent, such as ketone, ester and alcohol, or two or more mixtures thereof, is used, wherein the organic content of hydrate polymer, ultraviolet radiation chemical agent, hydrogen copolymer and non-ionic surfactant are increased respectively；the aqueous phase is prepared with distilled water and surfactant of the sodium lauryl ether sulfate or cocoamidopropyl betaine type or coconut fatty acid diethanolamide or sorbitan laurate 80 EO, or cetyl phosphate； and the dilution phase prepared with distilled water and surfactants, such as sodium lauryl ether sulfate, or cocoamidopropyl betaine or coconut satin acid diethanolamide or sorbitan laurate 80 EO. Claim 6: Production process of a thin film nanostructure of polymeric amphiphilic mixture with a high concentration of organic core for application against ultraviolet radiation, according to claim 5,It is characterized in that a core is formed by combining a copolymer of polyoxyethylene or polyoxypropylene and at least two UV radiation protection chemicals, and a mixture of polypropylene hydrophone polymers is used to form the core.Proceso de producción de una nanoestructura de película delgada de mezcla anfifílica polimérica con alta concentración de núcleo de carácter orgánico para aplicación contra la radiación ultravioleta, que comprende tres fases: orgánica, acuosa y fase acuosa de dilución, donde en la fase orgánica se utiliza un solvente orgánico como cetonas, ésteres y alcoholes, o también una combinación de dos o más de estos, donde es aumentado individualmente el polímero hidrófobo, el contenido orgánico de agentes químicos contra la radiación UV, el copolímero hidrófilo, y un tensioactivo no iónico； la fase acuosa es preparada con agua destilada y tensioactivo del tipo lauril éter sulfato de sodi
