摘　　要：植物纤维环保、价廉、可再生,将其应用于水泥基复合材料中不仅能提高材料的性能,还能降低混凝土造价,促进环境和谐与可持续发展。然而,植物纤维耐碱性较弱,限制了它在水泥基复合材料中的应用。本研究以丝瓜纤维为研究对象,将具有选择透过性的氧化石墨烯基膜包覆在纤维表面以提高其耐蚀性。结果表明,表面包覆氧化石墨烯基膜可以阻碍有害离子向纤维内部入侵,延缓纤维性能退化。Plant fibers are environmentally friendly,inexpensive and renewable.Applying them in cement-based composites can not only improve the properties of materials,but also lower the cost of concrete,and promote environmental harmony and sustainable development.However,plant fibers have weak alkali resistance,which limits their application in cement-based composites.The luffa fibers are chosen as the object of study,which are coated with graphene oxide(GO)-based membrane with selective permeability so as to improve their corrosion resistance.The results show that the GO-based membrane can prevent harmful ions from invading into the fibers,thus delaying the degradation of fiber properties.
