摘要
聚苯硫醚自一百年前第一次被合成以来虽已被广泛地研究,但对其结构的研究还是近年来的事。Tabor等人用X-射线衍射测定了聚苯硫醚的结构,确定其为正交结构,点阵参数为α=0.867nm,b=0.561nm,c=1.026nm。 由于高科技部门对具有导电性的高聚物的需求,人们在橡胶、高聚物中掺入导电材料粉末(如金属,石墨等),以得到具有不同电导率的高聚物材料,其电导率随导电粉末加入量的增加而加大,然后达到饱和。聚苯硫醚中加入石墨后,可获得电导率在10^(-4)
Microstructures of graphite/poly-phenylene sulphide compounds are studied by means of X-ray diffraction, transmission electron microscopy and fractography. It shows that the crystals of poly-phenylene sulphides have three kinds of structures, and no new phases are formed when graphite is added. Conductive polymers with different conductivties may be prepared by mixing different amount of graphite in it, forming conductive networks. The distribution- of graphite networks is a main factor to influence the conductivity of the conductive polymers.
