| Abstract: | Transparent plasticized gels with good mechanical, optical, and dielectric properties have important applications in various fields. We prepared a new gel using a poly(butylene terephthalate)‐co‐poly(alkylene glycol terephthalate) (PBT‐co‐PAGT) copolymer and a plasticizer, dibutyl adipate (DBA). This method improved the polymer crystallinity, and suppressed particle formation in cast‐films when the polymer was dissolved in 1,1,1,3,3,3‐hexafluoro‐2‐propanol, followed by solvent evaporation, and enabled uniform swelling of the polymer network by the plasticizer to form a transparent and flexible gel. The dielectric constants of the developed PBT‐co‐PAGT/DBA gels are much higher than those of PBT‐co‐PAGT films at low frequency. We believe that these PBT‐co‐PAGT/DBA gels could be used as photovoltaic, dielectric, and actuator materials. © 2015 Wiley Periodicals, Inc. J. Polym. Sci., Part B: Polym. Phys. 2015 , 53, 829–832 |
