“…The increased transparency is due to capillary action during water evaporation from the sheets causing the fibres to be densely packed together allowing more light to pass through the sheets. In addition the surface roughness is also reduced (Nogi et al, 2013). Mechanical properties of paper sludge nanopapers were found to be similar to a previous study on nanocellulose derived from dissolving cellulose sludge (Jonoobi et al, 2012); data are shown in Table 2.…”

Paper mills yield large volumes of sludge materials which pose an environmental and economic challenge for disposal, despite the fact that they could be a valuable source for cellulose nanofibres (CNF) production. The aim of the study was to evaluate the production process and properties of CNF prepared by mechanical fibrillation of never-dried and dried paper mill sludge (PMS). Atomic force microscopy (AFM) showed that average diameters for both never-dried and dried paper sludge nanofibres (PSNF) were less than 50 nm. The never-dried and dried sludge nanofibres showed no statistical significant difference (p > 0.05) in strength ~92 MPa, and ~85 MPa and modulus ~11 GPa and ~10 GPa. The study concludes that paper mill sludge can be used in a dried state for CNF production to reduce transportation and storage challenges posed on industrial scale.

“…Recently, cellulose nanofiber (CNF) films have been developed from various phytomass resources and have been shown to exhibit high transparency [28,29] and minimal surface roughness [30,31], as well as good flexibility. Compared with conventional plastics, CNF films are also known to display high strength [32,33] and thermal stability (a low coefficient of thermal expansion) [34,35], owing to the extended chain crystals of natural cellulose type I.…”

Enhancement of Luminance in Powder Electroluminescent Devices by Substrates of Smooth and Transparent Cellulose Nanofiber Films

Powder electroluminescent (EL) devices with an electric field type excitation are surface light sources that are expected to have a wide range of practical applications, owing to their high environmental resistance; however, their low luminance has hindered their use. A clarification of the relationship between the properties of the film substrates and the electroluminescence is important to drastically improve light extraction efficiency. In this study, powder EL devices with different substrates of various levels of surface roughness and different optical transmittances were fabricated to quantitatively evaluate the relationships between the substrate properties and the device characteristics. A decrease in the surface roughness of the substrate caused a clear increase in both the current density and the luminance. The luminance was found to have a direct relationship with the optical transmittance of the substrates. The powder EL device, which was based on a cellulose nanofiber film and was the smoothest and most transparent substrate investigated, showed the highest luminance (641 cd/cm2) when 300 V was applied at 1 kHz.

“…Recently, transparent paper made of CNs (NCC and NFC) had a representative thickness of 25-100 μm and a density of 0.8-1.5 g cm −3 , and attracted great attention because of its unique properties such as excellent flexibility [3,5,6,8,[89][90][91][92], superior surface smoothness [7,8,91], thermal stability [93,94], high optical transmittance [5,8,15,43,94,95], strong tensile strength [44,45,[47][48][49] and superior gas barrier performance in dry conditions [51-53, 87, 96-99]. These fascinating properties meet the stringent requirements of fabricating next generation 'green', transparent and flexible electronics on nanopaper.…”

Transparent paper made of cellulose for next generation 'green' electronic devices is a completely new concept that has attracted great attention over the past decade due to a variety of prominent properties of cellulose such as its natural origin, environmental safety and renewability. Various proof-of-concept transparent paper-based electronics have been demonstrated by scientists from all over the world. In this article, we first discuss the natural cellulose-based materials for transparent paper. We then summarize recent advances in the fabrication of transparent paper, including filtration, casting, extrusion and impregnation. The latest developments in transparent and flexible paper electronic devices are also demonstrated, such as photovoltaic devices, transistors, organic light emitting diodes and displays. Finally, we discuss the economically efficient routes for the mass production of transparent paper.
