This paper presents the chemical design and fabrication of optical film derived from biomass using eco-friendly nanoimprint lithography. The optical film derived from biomass with subwavelength structures was successfully demonstrated in specific desired properties. The linearly polymerized polysaccharide in optical film derived from biomass indicated two effects of high concentration of acrylate group in the side-chain terminus for highly sensitivity, and the ring components containing bulky disaccharide for suitable optical properties. The optical film derived from biomass is applicable to future development of antireflective material with subwavelength structures and suitable refractive index material as a chemical design concept.
