Abstract

An organic solvent-free sugar-based transparency nanopatterning material which had specific desired properties such as nanostructures of subwavelength grating and moth-eye antireflection, acceptable thermal stability of 160 °C, and low imaginary refractive index of less than 0.005 at 350-800 nm was proposed using electron beam lithography. The organic solvent-free sugar-based transparency nanopatterning material is expected for non-petroleum resources, environmental affair, safety, easiness of handling, and health of the working people, instead of the common developable process of tetramethylammonium hydroxide. 120 nm moth-eye antireflection nanopatterns images with exposure dose of 10 μC/cm 2 were provided by specific process conditions of electron beam lithography. The developed sugar derivatives with hydroxyl groups and EB sensitive groups in the organic solvent-free sugar-based transparency nanopatterning material were applicable to future development of optical interface films of biology and electronics as a novel chemical design.
