“…Considerable attention has been devoted to directly deposit conductive materials on the surface of flexible substrates using Mayer rod coating 24,25 , wet coating [26][27][28] , and vacuum filtration [29][30][31] . In our previous work [43][44][45] , we developed a pressured-extrusion papermaking process to fast fabrication of luminescent NFC nanopaper with high transparency (over 90%). In addition, pure AgNWs films can easily be oxidized to corrosion due to long time exposure in ambient air 33,34 .…”

Natural biomass based cellulose nanopaper is becoming a promising transparent substrate to supersede traditional petroleum based polymer films in realizing future flexible paper-electronics. Here, ultrathin, highly transparent, outstanding conductive hybrid nanopaper with excellent mechanical flexibility was synthesized by the assembly of nanofibrillated cellulose (NFC) and silver nanowires (AgNWs) using a pressured extrusion paper-making technique. The hybrid nanopaper with a thickness of 4.5 μm has a good combination of transparent conductive performance and mechanical stability using bamboo/hemp NFC and AgNWs cross-linked by hydroxypropylmethyl cellulose (HPMC). The heterogeneous fibrous structure of BNFC/HNFC/AgNWs endows a uniform distribution and an enhanced forward light scattering, resulting in high electrical conductivity and optical transmittance. The hybrid nanopaper with an optimal weight ratio of BNFC/HNFC to AgNWs shows outstanding synergistic properties with a transmittance of 86.41% at 550 nm and a sheet resistance of 1.90 ohm sq(-1), equal to the electronic conductivity, which is about 500 S cm(-1). The BNFC/HNFC/AgNW hybrid nanopaper maintains a stable electrical conductivity after the peeling test and bending at 135° for 1000 cycles, indicating remarkably strong adhesion and mechanical flexibility. Of importance here is that the high-performance and low-cost hybrid nanopaper shows promising potential for electronics application in solar cells, flexible displays and other high-technology products.

“…Among these characteristic emission spectrum peaks, the strongest one is centered at 612 nm ( 5 D 0 ? 7 F 2 ) and is ascribed to the typical electric-dipole transition, which is very sensitive in the host structure symmetry [40,41]. The transition observed at 593 nm ( 5 D 0 ?…”

“…CNF and CNC can serve as a matrix for inorganic phosphors. So Miao et al developed a simple method for highly-transparent luminescent nanopaper production with high heat resistance by grafting Eu, Sm, Tb lanthanide complexes onto TEMPO-oxidized CNF [43]. Chu with co-authors synthesized chiral nematic CNC luminescent films with YVO 4 :Eu 3+ nanoparticles [44].…”

Luminescent hydrophobic composite films based on nanocrystalline (CNC) and nanofibrillated (CNF) cellulose matrix with up-conversion MF 2 :Ho (M = Ca, Sr) particles and acrylic resin (ACR) as a coating have been synthesized. Flexible, translucent composite films were obtained by molding from the CNC/CNF suspensions with up-conversion particles. ACR coating was applied to the composite film by spraying. Studies have shown that ACR coating with a layer thickness of 7-10 µm provides hydrophobic properties for the films, increasing the water contact angle up to 100 ± 2 • with a simultaneous improvement in the luminescent properties. Transparency of CNC/CNF/MF 2 :Ho-ACR films in the visible and near IR region improves by 20-25 % without compromising the flexibility and thermal stability. The manufactured water-resistant composite films can be utilized as potential photonics materials, in particular for visualization of near-IR laser radiation and luminescent labels.
