biostudies-literatureUnknown8(4)Ding SCopper nanowire (CuNW) based flexible transparent electrodes have been extensively investigated due to their outstanding performances and low price. However, commonly used methods for processing CuNW transparent electrodes such as thermal annealing and photonic sintering inevitably damage the flexible substrates leading to low transmittance. Herein, a surface coating layer was demonstrated to protect the heat-sensitive polyethylene terephthalate (PET) polymer from being destroyed by the instantaneous high temperature during the photonic sintering process. The stable ceramic surface coating layer avoided the direct exposure of PET to intense light, further reduced the heat releasing to the bottom part of the PET, protecting the flexible PET base from destruction and ensuring high transparenRSC advances2109-2115https://www.ebi.ac.uk/biostudies/studies/S-EPMC9077247biostudies-literatureHighly conductive and transparent copper nanowire electrodes on surface coated flexible and heat-sensitive substrates.PMC9077247Jiu JDing SSuganuma KTian YfalseHighly conductive and transparent copper nanowire electrodes on surface coated flexible and heat-sensitive substrates.Copper nanowire (CuNW) based flexible transparent electrodes have been extensively investigated due to their outstanding performances and low price.
