【摘要】 本文通过微流体纺丝法实现了微米银线及独立导电银网[1,2]的制备。首先以粘度较高的聚N-乙烯基吡咯烷酮为纺丝材料,以硝酸银为银的前驱体,丙烯酸酯树脂作为光固化材料,实现了银纳米颗粒的原位生成,制备了不依赖于基底的独立的导电银网。研究表明持续激光照射诱导硝酸银的还原以及丝线表面致密银层的形成。测试表明银网方阻最小可达0.2?sq^-1。更多还原

【Abstract】 In this work, the preparations of micron silver fibers and free-standing silver mesh1,2 were achieved taking advantage of the microfludic spinning technique. In the experiment, aqueous solution of poly（N-vinylpyrrolidone） was employed as the spinning material due to its high viscosity. At the same time, silver nitrate acted as the silver precursor while the acrylate resin was used as the photopolymerized monomer. It was indicated that the continuous-wave laser induced the photoreduction of silver ions and closedly packed silver nanoparticles were formed at the surface of the fiber. The minimum sheet resistance was measured to be 0.2 ? sq^-1.更多还原
