摘要

利用直流瞬态电流测定了普通和掺杂低密度聚乙烯(LDPE)的载流子迁移率。钛酸钡作为强极性掺杂剂，二氧化钛作为半导体掺杂剂。得到的迁移率值为10/sup -10/ cm/sup 2/ v/sup -1/ s/sup -1/。结果表明，BaTiO/sub - 3/和TiO/sub - 2/的掺入量为1%，对聚合物的导电性能有较大影响。BaTiO/ sub3 /将载流子迁移率提高了三倍，同时也提高了聚合物的导电性。TiO/sub /将载流子迁移率提高了五倍。引入二氧化钛对电荷捕获和空间电荷形成进行了改进。

Determination of charge carrier mobility in doped low density polyethylene using DC transients

Charge carrier mobility was determined for plain and doped low-density polyethylene (LDPE) using DC transient currents. Barium titanate was used as a strongly polar dopant and titanium dioxide as a semiconductor dopant. The values of the mobility obtained were on the order of 10/sup -10/ cm/sup 2/ v/sup -1/ s/sup -1/. Results indicate that the inclusion of 1% by weight of BaTiO/sub 3/ and TiO/sub 2/ has a considerable effect on the conduction properties of the polymer. BaTiO/sub 3/ increased the charge carrier mobility by a factor of three and also increased the conductivity of the polymer. TiO/sub 2/ increased the charge carrier mobility by a factor of five. Charge trapping and space charge formation were modified by the introduction of titanium dioxide.<>
