英文摘要: Due to shortage of indium resources and brittleness of ITO, the wear-resistant, flexible, transparent, conducting films of metal nanowires (MNWs)-carbon nanotubes (CNTs) composite networks polyethylene terephthalate (PET)are prepared by the dip-coating and post-treatment process with optimized MNWs and CNTs and they are characterized with a high wear-resistance, a high visible light transparency, a low square resistance and an excellent heat conductance.The electrospinning and thermal reduction process is used to fabricate MNWs and the relation will be established between the MNWs characteristics and processing factors.By engineering of MNWs, CNTs and PET surfaces, the dispersion of MNWs and CNTs in solutions is investigated, leading a good interface strength between the PET substrate and networks of MNWs and CNTs. Then the behavior of tribology,visible light and electric carriers can be studied for the composite films. Based on the optimization of the processes for MNWs preparation, dispersion of MNWs and CNTs, dip-coating and post-treatment of composite films, the relationship can be realized among the composition, process, structure and properties.Consequently,the novel process for highly wear-resistant, flexible, transparent, conducting films of MNWs-CNTs/PET with a low cost can is developed. The interface s
