Abstract
The design concepts of an ecofriendly water-repellent film using the sugar-related organic compounds with fluorinated alkyl group derived from biomass are demonstrated to avoid various kinds of nanoimprint material pattern peeling, defects, particles, and contaminants in ultraviolet curing nanoimprint lithography. Developed sugar-related organic compounds with three glucose derivatives with ultraviolet curable groups or fluorinated alkyl group derived from biomass produced high-quality imprint images of pillar patterns with a 230-300 nm diameter and height of 200-250 nm. The ecofriendly waterrepellent film as a functional biomass material was indicated to achieve the high water contact angle of 102°, low surface free energy of 22.1, suitable refractive index of 1.42-1.50, and high transparency at the wavelength of 350-700 nm.
