Development of thin films deposited by plasma for polymeric materials photoprotection


Photodegradation of polymers limits the options for its use in exposure to the weather and reduces its useful life. Deposition of thin films of organosilicone by plasma on polymers increases its resistance to photodegradation without interfering in aspects such as color and brightness due to its transparency and nanometric dimension. From previous results obtained in a doctoral project, with up to 80% less carbonyl formation during accelerated aging of polypropylene, two results are expected: A) to develop optimum conditions for the deposition of thin films of organosilicone by plasma, facilitating the transposition for product development, with more continuous and flexible thin films on polymer, with good resistance to the photodegradation in polypropylene, and; B) to study the photodegradation of the thin films of organosilicone, an unpublished subject in the literature.
