We study the mechanical behavior of Au nanomeshes (AuNMs) based on finite element analysis (FEA) simulation and deformation tests. The simulated results of mechanical flexibility indicate that polyethylene terephthalate (PET) substrate can release the stress of AuNMs under mechanical stretching and bending, the displacement of stretched AuNMs yields a 2% promotion, and the displacement of bent AuNMs yields a 3.5% promotion under buffering of PET substrate at 5 GPa yield strength of nanoscale Au. The stress and displacement distribution of the AuNMs/PET is demonstrated and analyzed. The further deformation tests of AuNMs under compressive and tensile loading indicate that the simulation data are in good agreement with experimental results. This paper is conducive to understanding the mechanical behavior and corresponding structural response and structural fracture dynamics of AuNMs.

Using sustainable cellulose and its derivatives to prepare optical diffuser is an economic and green approach. Herein, we report a novel optical diffuser constructed by interfacial assembly of cellulose ether (CE) and polymer complex particles (PCP) on flexible and transparent poly(ethylene terephthalate) (PET) substrate. Owning to the rich hydroxyl groups of CEs, the complex thin film can be further crosslinked by thermal treatment which greatly improves the optical diffusion performance and durability. Without crosslinking, haze (H) of the cellulose complex film is about 81 %, and the film will dissolve in high pH value solution. While after the proper crosslinking, H of the film increases to 95 %, and the film can resist the erosion of high pH solution. Moreover, CE/PCP complex film shows improved anti-bending capacity compared with commercially available optical diffuser for liquid crystal display .

Direct synthesis of silver conductive film on PET substrate by inkjet printing silver citrate conductive ink was presented in this paper. This kind of conductive ink contained silver citrate as silver precursor, 1,2-diaminopropane as complex agent dissolving the silver salt and methanol and isopropanol as a media adjusting the viscosity and surface tension. The formation of silver-amine complex reduced the decomposition temperature from 180 °C to 135 °C, thus the ink could be cured at relatively low temperature. The film reached the lowest resistivity of 17 μΩ cm after cured at 150 °C for 50 min, 3.1 μΩ cm at 230 °C and possessed high reflection and excellent adhesive property. Electrical conductivity, surface morphology and composition were investigated by four-point probe method, scanning electron microscope (SEM) and energy dispersive X-ray spectroscopy (EDS). It is demonstrated how the cured condition affects the silver film. Moreover, radio-frequency identification (RFID) antenna was fabricated by inkjet printing, which opens up routes for the flexible electronics fabrication.

Flexible conductive copper patterns with low electric resistance, good adhesion, and high stability were successfully prepared on heat-sensitive polyethylene terephthalate (PET) substrate by combining the inkjet print with copper nanoparticles (Cu NPs) conductive ink and electroless plating (ELP) copper at room temperature. The Cu NPs served as the catalysts to promote copper ions electroless deposition on PET surface. Dimethylaminoborane (DMAB) was used as the reductant to place poisonous formaldehyde in the electroless plating process. The Cu patterns had a strong adhesion with PET substrate modified by 3-Mercaptopropyltriethoxysilane (MPTES) and would not fall even after 4000 cycles bending test. The electric resistivity of patterns could be as low as 5.43 μΩ·cm, which is about three times that of bulk copper. The minimum sheet resistance of the patterns was 54 mΩ/sq and had little change in the atmosphere for five months, that showed the patterns had an excellent anti-oxidation performance.

Silver nanowires (AgNWs) thin films have emerged as promising next-generation transparent conductive electrodes (TCEs), and increasing the opto-electrical properties and long-term stability of AgNWs based TCEs is now a major research focus. In this work, a smooth, flexible, electrically conductive and highly stable transparent AgNWs-silica nanoparticles composite TCE has been successfully manufactured via coating an aqueous AgNWs-silica sol composite conductive ink on a PET substrate through the Mayer rod method. The effects of particle size and concentration of silica sol on the smoothness, opto-electrical properties and stability of AgNWs based TCEs were investigated in detail, and the mechanisms of the decoration of AgNWs by silica sol nanoparticles and welding of the network junction are discussed briefly. The TCE based on AgNWs reinforced with 50 nm silica nanoparticles (80 ppm concentration of silica sol) possesses a smooth surface with an RMS value of 9.45 nm, and superior opto-electrical properties with a sheet resistance of 28 Ω sq−1 and a transmittance of 97%. The resistance of the resultant AgNWs-silica composite TCE remains nearly constant after bending for 1000 cycles or exposure to Na2S solution for 300 s, indicating high stability. The newly designed AgNWs-silica composite TCE is a promising flexible and transparent electrode to be applied in next-generation flexible electronic devices.
