实验制备了模板，其直径0.1μm～1μm，长度1μm～20μm，长经比为10～20；采用相同模板制备导电聚合物微管，长度范围在10μm～20μm之间。随着反应温度的升高，甘氨酸铜微管的管径随之变大。这是因为温度决定化学反应能否进行，影响过饱和度和扩散速度，一般而言，温度越高，晶粒平均粒度越大，粒度分布范围越宽。 根据实验所得的产物其X-射线粉末衍射曲线呈馒头峰是非晶态，没有出现模板甘氨酸铜的衍射峰。聚合产物的红外光谱在在1577和1457cm-1是吡咯环的基本振动引起的吸收峰，1303和1040cm-1是由于平面=C-H振动引起的吸收峰，而C-N键伸缩振动和C-H的非平面摇摆振动分别导致红外图谱1175和783cm-1存在所吸收峰，与普通合成的聚吡咯吻红外光谱基本一致。 |

Experimental Preparation of the template, the diameter of 0.1μm ~ 1μm, the length of 1μm ~ 20μm, length by the ratio of 10 to 20; use the same template preparation of conducting polymer micro-tubes, the length of the range of between 10μm ~ 20μm. With the reaction temperature, glycine copper micro-tubes become larger then the diameter. This is because the temperature of the decision whether to carry out a chemical reaction, affected the proliferation rate of saturation and, in general, the higher the temperature, the average grain size the greater the more wide range of particle size distribution. According to the experimental product derived from its X-ray powder diffraction peak curve bread is amorphous, glycine template no diffraction peak of copper. IR spectra of polymerization products in the 1577 and 1457cm-1 is a pyrrole ring fundamental vibration caused by the absorption peak, 1303 and 1040cm-1 is due to plane = CH vibration absorption peak, while the CN bond and the CH stretching vibration of the non-planar rocking vibration, respectively, leading to infrared map of 1175 and 783cm-1 the existence of the absorption peak, and general synthesis of polypyrrole infrared spectra are basically the same as kiss. |

As the rise of the reaction temperature, the diameter of the glycine copper micro-tubes become larger. This is because the temperature decides whether a chemical reaction could be carryed out, affects the saturation and proliferation rate.In general, the higher the temperature is, the wider the range of the particle size distribution. |
