摘要：
Bariumtitanate/epoxy resin (BT/ER) composite with high permittivity was obtained through graft modification on the ER matrix. Polyether polyols were employed to enhance the molecular polarity, which brought more polar oxygen atoms and produced more ester groups in the cured epoxy resin. The permittivity of epoxy matrix film was effectively enhanced (increased from 3.91 to 4.82 at 10(3) Hz) while the dielectric loss was nearly unchanged. The permittivity of the composite films containing the same amount of BT fillers improved from 18.91 to 28.73. Meanwhile, the increment of dielectric loss was not obvious. Both of the modified matrix and composite films showed excellent thermal stability. (C) 2014 Elsevier B.V. All rights reserved.
