【Abstract】 In this paper, the polymethyl methacrylate(PMMA) optical thin film was prepared by sol-gel and dip coating approach. The transmission spectrum of film was measured by a UV-Vis spectrophotometer. The refractive index and thickness of the film were calculated via the UV spectrophotometry. Then the effects of pulling speed and heat treatment temperature on the thickness and refractive index of the film were investigated. The experimental process covering material preparation, testing and performance control was carried out completely and effectively. We believe that the comprehensive application of the relevant knowledge of materials, physics, chemistry, optics and organic polymers can help students systematically practice their professional skills, cultivate comprehensive ability and scientific research innovation consciousness.更多还原
