Nanomorphology of Polymer Blends for a Light-Scattering Thermosetting Plate Based on Self-Assembly

Abstract

An approach to optical plate production using the nanomorphology of polymer blends in lightscattering thermosetting plates based on self-assembly was investigated without using the conventional approach of blending nanoparticles such as silica sol, zirconia sol, phosphor, or chromophore into the polymer matrix. For this purpose, two specified polymers having carboxylic acid and epoxy groups were blended using a light-emitting diode for use in liquid crystal displays. The developed light-scattering thermosetting plate containing poly(acrylic acid) with the carboxylic acid at four different weight average molecular weights in a cycloaliphatic epoxy polymer was shown to achieve regular nanoparticles of 30-350 nm for light-scattering, light-scattering rates of over 10% at a wavelength of 300 nm, a thermal stability up to 230 8C, O 2 gas barrier properties approximately 50 times smaller than that of polyethylene, and solvent resistance after polymerizing.

Insights on Light Dispersion in Semi‐Alicyclic Polyimide Alignment Layers to Reduce Optical Losses in Display Devices

“…The researches in the area of flat panel industry are still focused on the liquid crystal displays (LCDs) owing to their advantageous low power consumption, light weight, and image contrast. [1,2] The main components of such devices are the backlight unit (BLU), the panel with transistors, the polarizers, the color filters, and the nematic liquid crystal (NLC) sandwiched between the transparent electrodes (e.g., indium tin oxide [ITO]). The performance of LCDs is determined by the NLC organization in the absence/presence of an electrical field, which in turn affects the transmitted light at each picture element.…”
