Wurtzite-type Zn 1-x Co x Onanofibers were successfully fabricated by sol-gel method combined with electrospinning technology. The as-prepared fiber samples were characterized by TGA-DSC, XRD, FTIR and SEM techniques. The infrared emissivity of the product were tested using an IR-2 infrared emissivity analyzer. The results show that wurtzite structure is formed at 600°C for 2h. These nanofibers have diameters in the range of 60-100nm. As the doping concentration increases, The infrared emissivity of the sample decreases first and then increases slowly. When x = 0.04, the lowest infrared emissivity is 0.76.This makes Zn 1-x Co x O nanofibers have a good prospect in the infrared emissivity nanomaterials.
