摘要：

Zinc oxide (ZnO) nanowires were grown on silicon substrate by using polar polymer (such as PAM) long-chain as self-assembling grid backbone via polymer soft-template controlling nucleation of ZnO nanodots and oriented growth of ZnO nanowires. The kinetics of the crystallization of ZnO nanowires and the thermal decomposition of the complex PAM-Zn2+ during preparation were investigated by means of differential scanning calorimetry (DSC) and thermogravimetry (TG), and the relationship between the reaction rate and time, concentration and temperature were obtained, [GRAPHICS] The calculation results are in good accordance with the experiments. It is found that one dimensional wire-like growth model is in favour of the nucleation and crystal growth behavior of ZnO nanowires, and the ZnO nanowires possess perfect crystal structure.
