A study on the improvement of mechanical and chemical properties in nano semiconducting materials

In this paper, we have investigated mechanical and chemical properties by changing the content of carbon nanotube, which is component part of semiconductive shield in underground power transmission cable. Specimens were made of sheet with the eight of those for measurement. The condition of specimens was a solid sheet. Chemical properties of specimens was measured by FT-ATR (Fourier Transform Attenuated Total Reflectance). Stress-strain of specimens was measured by TENSOMETER 2000. A speed of measurement was 200[mm/min], ranges of stress and strain were 400[Kgf/Cm] and 600[%]. We could observe functional group (C=O, carbonyl group) of specimens through FT-ATR. From these experimental result, the concentration of functional group (C=O) was high according to increasing the content of carbon nanotube. We could know CNT/EEA was excellent more than other specimens from above experimental results. In Addition, the elongation ratio was decreased, and yield strength was increased according to increasing the content of carbon nanotube. Also, from these experimental result, we could know that a small amount of CNT/EEA has a excellent mechanical and chemical properties.
