双向拉伸聚丙烯(BOPP)是最重要的储能电容器用介质膜之一。BOPP薄膜的工作电场高达650kV/mm，会导致大量的空间电荷注入，这对电容器是非常危险的。用热脉冲法研究了BOPP薄膜在不同工作温度和不同直流电场下的空间电荷行为。在室温下，在直流电场作用下，BOPP薄膜中观察到了不对称的双极空间电荷注入，并且随着实验温度的升高，负电荷的积累逐渐占优势。在温度为70℃时，整个样品中只能观察到负的空间电荷，这主要是由于不同数量的相反极性注入电荷的相互移动所致。结果表明，空间电荷积累产生的局部电场可达外加电场的80%。
Biaxially oriented polypropylene (BOPP) is one kind of the most significant dielectric films for energy storage capacitors. The operating electric field up to 650 kV/mm for the BOPP film can lead to numerous space charge injection, which would be very dangerous to the capacitor. In this investigation, space charge behavior in the BOPP films under various operating temperatures and DC electric fields was studied by the thermal pulse method. At room temperature, the asymmetric bi-polar space charge injection was observed in the BOPP films under DC electric field, and the accumulation of negative charge become dominant gradually with the increase of the experimental temperature. At temperature 70 °C, only negative space charge can be observed in the whole bulk, which could mainly be attributed to the mutual shifting of the opposite polarity injected charge with different amounts. As the consequence, the local electric field generated by accumulated space charge can be up to 80% of the applied field.
