  • Publication number: 20220275151
    Abstract: A method of making polyesters and polyurethanes from biomass-derived polyols. The polyol is biomass-derived and has the structure: wherein dashed bonds are single or double bonds and R is selected from the group consisting of —OH and ?O. Polyurethanes are made by reacting the polyol with a diisocyanate. Polyesters are made by reacting the polyol with a dicarboxylic acid.

  • Publication number: 20200070403
    Abstract: Provided are a method of producing a nanoparticle device and a nanoparticle device. The method of producing a nanoparticle device may be economical due to use of a hydrogel, may be easy to design in terms of mass production processes, and may reduce manufacturing times to 1/100 to 1/10 of the technology of the related art. In addition, a nanoparticle device may be produced in various designs by stably realizing a 3D pattern and pattern stacking, and may have highly uniform nanoparticle dispersion and excellent electrical activity through the removal of a surfactant without damaging the pattern. The nanoparticle device produced according to the production method may have excellent electrical activity due to nanoparticle uniformity pattern accuracy and thus may be applied to pattern stacking which could not be implemented by methods of the related art.
