摘要：用环氧氯丙烷（EPI）对氧化石墨烯（GO）进行共价键改性，制备了环氧改性氧化石墨烯（EPGO），再
将 EPGO 共混水性聚氨酯（WPU）制得了含有不同质量分数 EPGO（以水性聚氨酯有效质量计）的 EPGO/WPU
复合膜，通过 FTIR、XRD、TEM 表征了 EPGO 的结构和形态，并测试了成膜拉伸性能、耐磨性能。结果表明：
EPGO 的添加可以明显提高水性聚氨酯膜的拉伸强度，当添加 0.8%（质量分数）的 EPGO 时，复合膜的拉伸强

Abstract: Epoxy modified grapheme oxide (EPGO) was prepared via covalent bonding between
epichlorohydrin (EPI) and graphene oxide (GO) and was characterized by FTIR, XRD and TEM. The
obtained EPGO mixed with waterborne polyurethane (WPU) emulsion to produce EPGO/WPU composite
films containing different mass fraction of EPGO (based on the mass of effective components of WPU
emulsion). The tensile properties and abrasion resistances of these films were tested. The results revealed
that the addition of EPGO could obviously increase the tensile strength of the modified WPU film. When
the addition amount of EPGO was 0.8%, the tensile strength of the composite film reached 12.9 MPa,
which was an improvement of 67.5% compared with that of the blank film (without EPGO). The Young's
modulus increased by 36.4%, and the abrasion resistance improved remarkably. All these indicated that
EPGO addition had an enhancement effect on the waterborne polyurethane film.
