中文摘要：
通过熔融共混方法制备了具有双连续相结构的丙烯腈-丁二烯-苯乙烯／聚对苯二甲酸乙二醇-1，4-环己烷二甲醇酯（ABS／PETG）共混物；同时研究了炭黑、石墨和镍粉等对ABS／PETG共混物导电性能、维卡软化点和接触角的影响。结果表明，ABS／PETG共混物的电导率随着炭黑用量的增加而增加，并当炭黑质量分数达到20％时，ABS／PETG共混物电导率达到120S／m；当用石墨和镍粉部分取代炭黑后，ABS／PETG共混物电导率增加效果不如炭黑好；ABS／PETG共混物接触角随着炭黑或石墨含量的增加而增加，耐水性增强，且石墨比炭黑更有利于提高材料的耐水性能，但是当添加镍粉后，ABS／PETG共混物的接触角反而下降，耐水性变差；实验表明，炭黑和镍粉都可提高ABS／PETG共混物的耐热性能，但是当镍粉含量超过-定数值后，ABS／PETG共混物的耐热性能急剧下降。
英文摘要：
Bicontinuous phase structure of ABS/PETG composite was prepared by melt blending method. The influences of carbon black, graphite and nickel on the conductivity, contact angle and VEKA softening point of ABS/PETG composite were studied in detail. The results showed that the conductive properties of ABS/PETG blends increased with increasing amount of carbon black, when the content of carbon black was 20%, the conductivity of the ABS/PETG was at 120 S/m. When graphite replaced part of carbon black, the increase in conductivity was not more obvious than that of the carbon black. The contact angle increased with the increase of the carbon black and graphite as well as the water resistance. But when adding the nickel, the contact angle of the ABS/PETG blends decreased, and the water resistance got poor. The results showed both the carbon black and graphite could increase the heat resistance of ABS/PETG material, but when adding nickel powder materials, the heat resistance was poor.
