摘 要：将生物基高分子材料与石墨共球磨或超声处理，可同时实现石墨的剥离和两种材料 的杂化。所得杂化材料兼具两组分的优点，如良好的导热、导电性能、阻隔性能及生物相容性 等。然而，目前用于杂化的生物基高分子材料多为非水溶性材料，其在水溶液中对石墨烯表 面的浸润性差，难以在二者之间形成强的相互作用。因此选用具有良好水溶性的羧甲基纤维 素钠（CMC）辅助球磨剥离石墨，制备了石墨烯/羧甲基纤维素钠杂化材料。详细探究了球磨 时间和 CMC 浓度对所得杂化材料产率及浓度的影响。研究结果表明，得益于 CMC 的增黏作 用及其对石墨烯表面的良好浸润，CMC 的存在极大地促进了石墨的剥离。透射电子显微镜 （TEM）及原子力显微镜（AFM）的表征也证实了 CMC 分子紧密附着在石墨烯片层表面。得 益于 CMC 优异的水溶性，所得石墨烯/羧甲基纤维素钠杂化材料（GN/CMC）可在水溶液中良 好分散。由该杂化材料制得的薄膜不但导电率达 2 000 S · m−1 而且具备优异的湿度驱动的动 态热管理能力。

Abstract：Co-ball milling or ultrasonic treatment of bio-based polymer materials with graphite can simultaneously achieve the exfoliation of graphite and hybridization of the two materials. The resulting hybrid materials offer combined benefits from both components， including good thermal and electrical conductivity， moisture and gas barrier properties， as well as biocompat⁃ ibility， among others. However， most of the bio-based polymer materials currently used for hybridization are non-water-soluble， and their poor wettability to the graphene surface in aque⁃ ous solution makes it difficult to form strong interactions between the two. In this paper， graphene/sodium carboxymethyl cellulose hybrids were prepared by using sodium carboxymethyl cel⁃ lulose （CMC）， which has good water solubility， to assist in ball milling to exfoliate graphite. The effects of ball milling time and CMC concentration on the yield and concentration of the resulting hybrid materials were investigated in detail. The results showed that the presence of CMC greatly facilitated the exfoliation of graphite thanks to the viscosity-enhancing effect of CMC and its good infiltration on the graphene surface. The characterization by transmission elec⁃ tron microscopy （TEM） and atomic force microscopy （AFM） also confirmed that the CMC mol⁃ ecules were tightly attached to the surface of graphene lamellae. Thanks to the excellent water solubility of CMC， the resulting graphene/sodium carboxymethylcellulose hybrid （GN/CMC） can be well dispersed in aqueous solution. The films made from this hybrid material not only have an electrical conductivity of 2 000 S · m−1 but also have excellent humidity-driven dynamic thermal management capabilities.
