OXIDATION GRAPHITE SURFACES AND THE RESEARCH PROGRESS AND POLYMER COMPOSITELIU JiaAbstract: the graphite surfaces is currently the only discovery existing 2 d free state atomic crystal, it is building zero d fullerenes, a d carbon nanotubes, 3 d body in the hybrid carbon graphite sp2 the basic structure of unit, have a lot of strange electronic and mechanical properties. In recent three years, graphite surfaces from concept on 2 d materials into reality materials, in the chemical and physical circles are caused a sensation. Through the review of graphite oxide and oxidation graphite surfaces of the preparation, structure, modification of polymer and the pound, and prospects the graphite surfaces and the research prospect of posite materialsKey words: oxidation graphite surfaces。5 結束語綜上所述, 目前的制備技術存在氧化石墨烯及其聚合物尺寸小且分布不均、難以批量生產(chǎn)以及性能難以精確控制等瓶頸問題;另外, 現(xiàn)有的表征手段耗時、容易破壞石墨烯的晶格結構, 也制約著石墨烯的進一步研究。讓科學家震驚的是,石墨烯比鉆石還強硬,它的強度比世界上最好的鋼鐵還高100倍!美國機械工程師杰弗雷在5nm大小的石墨烯片上, 只要有一小段邊緣是鋸齒型的,就會將材料由半導體變?yōu)閷w。石墨烯與碳納米管不同, 它是平面結構, 因此更適合傳統(tǒng)芯片的制造工藝。結果顯示,鋸齒型邊緣(zigzag edge) 表現(xiàn)出了強邊緣態(tài), 而椅型邊緣(armchair edge)卻沒有出現(xiàn)類似情況。石墨烯很有可能成為組建納米電子器件的最佳材料, 可能是下一
