CNT 직경에 따른 CNT-Polyamide 복합체의 특성 변화

다국어 초록 (Multilingual Abstract)

The effect of CNT diameters on properties of CNT-polyamide composites were investigated such as electrical conductivity, tensile strength and thermal conductivity. To get different diameter distributions of CNTs, several portions of Mo and Fe in Mo-Fe/MgO catalysts were synthesized by a combustion method at 600℃. And all CNTs growed at 900℃ with 3 SLM methane and 1 SLM hydrogen for 40min. Four kinds of CNTs with different diameter distributions, such as 1~3㎚, 3~7㎚, 7~13㎚, and 10~30㎚, were selected to make CNT-polyamide composites. Each composite was manufactured by a solution mixing using bar-type ultra-sonicator in the CNT portions from 1phr to 50 phr. And electrical conductivity, tensile strength, and thermal conductivity were measured. Three properties of CNT-polyamide composite, manufactured with 10㎚ diameter, were more excellent compared to other composites, with electrical conductivity 10°Ω at 7phr, thermal conductivity 2.4.W/mK at 40phr, tensile strength 60㎫ at 30phr. CNTs with diameter 10㎚ were superior to other diameters for the multi-functional composite such as CNT-polyamide Composites.
