Optically Transparent Cellulose Nanofiber-Based Materials
Synonyms
Bio-based nanocomposites; Substrate for roll-to-roll processing
Definition
If the dispersed phase of two-phase composites is nanoscale and much smaller than the optical wavelength, light scattering can be avoided without perfect matching of refractive index for the two phases.
Introduction
The rapid development of optoelectronics technology is making flexible displays by roll-to-roll process a soon-to-be-available reality. Among these display technologies, the organic light-emitting diode (OLED) has received a lot of attention because of its attractive features for display applications. However, commercially available OLEDs are fabricated on glass substrates. Although flexible plastics are expected as alternatives to existing glass substrates, no prospect of actually using plastics has yet emerged due to its high coefficient of thermal expansion (CTE). Foldable plastics, in particular, have extremely large CTEs, exceeding 200 ppm/K. As multilayers of different materials are...
