报道了一种有效的低温生长方法，在PET织物上制备了六角取向的ZnO纳米棒阵列。通过X射线衍射（XRD）、场发射扫描电子显微镜（FE-SEM）和紫外线防护因子（UPF）详细研究了衬底预处理和C6 H12 N4浓度对ZnO纳米棒阵列结构的影响。结果表明，衬底预处理、C6 H12 N4浓度对ZnO纳米棒阵列的生长确实有很大的影响。在衬底上引入ZnO种子层，在n（C6 H12 N4）：n[Zn（NO3）2]=1：1，T=90°C，t= 3 h的条件下，在预处理的PET织物上得到了直径为40- 50 nm，长度为300- 400 nm的ZnO纳米棒阵列。在本研究中，在PET织物上生长的ZnO纳米棒具有480.52的紫外线防护因子，与未处理的PET织物相比，显示出优异的抗紫外线辐射的防护。
An effective low-temperature growth method to fabricate hexagonally oriented ZnO nanorod arrays onto PET fabrics is reported. The effect of substrate pre-treatment and C6H12N4concentration on the structure of ZnO nanorod arrays were investigated in details by X-ray diffraction (XRD), FE-SEM and ultraviolet protection factor (UPF). The results show that substrate pre-treatment, C6H12N4concentration indeed have great influence on the growth of ZnO nanorod arrays. It is indispensable to introduce a ZnO seed layer on the substrate and under growth condition of n(C6H12N4):n[Zn(NO3)2]=1:1, T=90°C, t=3h, the well-aligned ZnO nanorod arrays with 40–50nm in diameter and 300–400nm in length were achieved on the pre-treated PET fabrics. The ZnO nanorods grown on PET fabrics possessed an ultrahigh ultraviolet protection factor of 480.52 in this study, indicating an excellent protection against ultraviolet radiation in comparison with the untreated PET fabrics.
