In order to study the influences of non-isothermal crystallization on space charge characteristics in low-density polyethylene(LDPE) at temperature fields, three types of LDPE samples with different annealing rates were prepared, denoted as LDPE-I(ice water), LDPE-A(air), and LDPE-S(slow). Space charge property was tested at temperature fields(20 ℃, 40 ℃, and 60 ℃) based on the pulsed electro-acoustic(PEA) method. The results show that a lower annealing rate benefits to the crystallization of LDPE, resultin...
