摘要: In this article, epoxy shape-memory polymer (ESMP) reinforced with 1 wt % thermally reduced graphite oxide (TrGO) was fabricated by solution blending and three-roll mill (TRM) mixing, respectively. Both techniques allowed a uniform TrGO dispersion in ESMP matrix, the TRM mixing lead to an exfoliation of worms. Compared pristine ESMP, TrGO/ESMP composites showed 36.4–41.1% increase Young's modulus 38.1–44.1% improvement tensile strength. The composite had T5% (the temperature where material lost 5% its initial weight) 16.4°C higher than pure ESMP. significant recovery force 84.4% 311.1% obtained © 2015 Wiley Periodicals, Inc. J.
