Research Progress on Graphene Oxide Nanoribbons Nanohybrids and Graphene Nanoribbons

氧化石墨烯纳米带杂化粒子是将氧化石墨烯纳米带(GONRs)与其他纳米粒子经π-π键、氢键等结合方式复合在一起,通过这种特殊的结合形态一方面可以有效地防止GONRs的聚积,另一方面新的纳米粒子的引入能够赋予该杂化材料某些特殊的性能,从而有利于充分发挥GONRs杂化材料在聚合物改性等领域的综合性能。本文综述了氧化石墨烯纳米带杂化粒子的制备方法、性能和应用现状。此外,针对GONRs的还原产物石墨烯纳米带(GNRs)的结构、性能、制备方法及其应用领域也进行了系统性地论述。相关研究表明,氧化石墨烯纳米带杂化粒子的设计与制备是氧化石墨烯纳米带迈向实用领域的一个有效途径,而石墨烯纳米作为石墨烯的一种特殊结构的二维变体,继承了石墨烯优良的导电和导热等性能,同时特殊的边缘效应,因而呈现出了更广阔的应用潜力。

Graphene oxide nanoribbons （GONRs） nanohybrids were prepared by combining GONRs and other nanoparticles together via the forms ofπ-π bond or hydrogen bond. This specific combina- tion form can effectively prevent GONRs accumulation, on the other hand, the introduction of new nanoparticles can bring some special properties to the nanohybrids, which is beneficial to give full play to the comprehensive performance of GONRs nanohybrids in polymer modification and other applica- tion areas. In this paper, the preparation methods, properties, and application status of GONRs nano- hybrids were reviewed in details. Moreover, the structure characteristics, properties, preparation methods and applications of GNRs （as the GONRs reduction product） were also discussed. The relat- ed studies have shown that, design and preparation of GONRs nanohybrids is an effective way to the practical application of GONRs, and GNRs as a special two-dimensional variant of graphene, which inherits excellent electrical properties and thermal conductivity from graphene, meanwhile, the special edge effect shows a broader application prospect.
