Highly transparent paper with tunable haze for green electronics
The ability to manage the light scattering effect of transparent paper without sacrificing its original high transmittance is critical for the application in optoelectronics since different devices have different requirements for the optical properties. In this paper, we study highly transparent paper with a tunable transmission haze by rationally managing the ratio of nanoscale cellulose fibers to macroscopic cellulose fibers. The transparent papers present a largely modulated light scattering behavior while retaining a transparency of over 90%. Various measurements are then used to characterize the optical properties of the different transparent papers in detail. To demonstrate the device applications in green electronics, we fabricated a top gated transistor with MoS2 on the transparent paper containing 100% NFC that leads to an excellent on/off ratio. The highly transparent paper with a controllable light scattering behavior has an unprecedented potential for applications in optoelectronic devices as a substrate or a functional component.
