摘要
用热释电流法(TSC)研究了环氧树脂/玻璃布复合材料.该复合材料的热释电流谱分别在99、112和163℃对应出现三个热释电流峰即α_(1c)、α_(2c)和ρ_c。研究分析了各峰的归属:α_(2c)峰是由于树脂基体的偶极取向极化产生的,对应于树脂的玻璃化转变;α_(1c)峰是由界面区的偶极极化引起的;ρ_c 峰是由界面区域内的空间电荷极化造成的。
Thermally stimulated current (TSC) of epoxy-glasscloth composites has bccn stud:ed in
the temperature range from -140℃ to 190℃.Three peaks near 99(α_(1c)),112(α_(2c)),and 163℃(ρ_c)
are observed in the composites.The origins of these TSC pcaks were investigated.The α_(2c) peak
is attributed to dipole orientation polarization associatcd with the glass transition of resin ma-
trix.The α_(1c)peak probably arises from dipole polarization in boundary regions bctween the
resin matrix and glasscloth.The ρ_cpeak is attributed to interfacial space charge polarizations.
