dc.description.abstract | Bamboo is a convenient and low-cost material. Its lattice structure is (C6H12O5)n network, so it has very strong characteristics. The vascular bundles can be used to accommodate sodium chloride solutions and metal nanoparticles.
In this experiment, the bamboo slices are divided into two series of outer A and inner B. According to X-ray diffraction analysis, the intensity of the X-ray diffraction peak can be inferred that there are differences amount of various metals incorporated. The bamboo slice was cut along the vascular bundle to scan the section to prove that NaCl and metal are indeed embedded in the bamboo slices. Finally, the X-ray diffraction pattern from wet to dry is measured, and the result shows that the diffraction peak of NaCl is enhanced, and it can be confirmed that Na+ and Cl- assist the conduction.
In the A series of samples, applied voltage of 10 V to the dried samples to measure the current value, and it is calculated that the maximum conductivity of each sample under dry conditions is only 7.5 times of dry bamboo. Under wet conditions, the conductivity can be increased to 3910 times. After adding a temperature difference between the positive and negative poles, the current can be enhanced to 1.96 times higher than the original current.
In B series, only wet samples are measured, and the conductivity can reach 7168 times of that of dry bamboo. The current is increased to 1.16 times after the temperature difference is added. Cut the bamboo slice into three parts and then took two of them in parallel for current testing, which showed that the current after paralleling was about twice that of the original sample. Finally, it is calculated that the ZT value of the B series samples about 10-7. From series of experiments, it is known that needs to be strengthened is the conductivity. | en_US |
