Abstract

A facile method for preparing functionalized graphene oxide single layers with nitroxide groups is reported herein. Highly oxidized graphite oxide (GO=90.6%) was obtained, slightly modifying an improved Hummer's method. Oxoammonium salts (OS) were investigated to introduce nitroxide groups to GO, resulting in a one-step functionalization and exfoliation. The mechanisms of functionalization/exfoliation are proposed, where the oxidation of aromatic alcohols to ketone groups, and the formation of alkoxyamine species are suggested. Two kinds of functionalized graphene oxide layers (GOFT1 and GOFT2) were obtained by controlling the amount of OS added. GOFT1 and GOFT2 exhibited a high interlayer spacing ( = 1.12nm), which was determined by X-ray diffraction. The presence of new chemical bonds C-N (9.5 %) and O-O (4.3 %) from nitroxide attached onto graphene layers were observed by X-ray photoelectron spectroscopy. Single-layers of GOFT1 were observed by HRTEM, exhibiting amorphous and crystalline zones at a 50:50 ratio; in contrast, layers of GOFT2 exhibited a fully amorphous surface. Fingerprint of GOFT1 single layers was obtained by electron diffraction at several tilts. Finally, the potential use of these materials within Nylon 6 matrices was investigated, where an unusual simultaneous increase in tensile stress, tensile strain and Young's modulus was observed.

摘要

本文报道了一种制备带有氮氧化物基团的功能化氧化石墨烯单层的简便方法。通过对改进的Hummer法进行微调，获得了高氧化度的氧化石墨（GO = 90.6%）。研究了氧鎓盐（OS）将氮氧化物基团引入GO的情况，从而实现一步功能化和剥离。提出了功能化/剥离的机制，其中包括芳族醇氧化为酮基以及烷氧基胺物种的形成。通过控制OS的添加量获得了两种功能化氧化石墨烯层（GOFT1和GOFT2）。GOFT1和GOFT2表现出较大的层间距（ = 1.12nm），这是通过X射线衍射确定的。通过X射线光电子能谱观察到石墨烯层上附着的氮氧化物产生了新的化学键C-N（约9.5%）和O-O（约4.3%）。通过高分辨透射电子显微镜观察到GOFT1的单层，其非晶区和结晶区的比例为50:50；相比之下，GOFT2的层表现出完全非晶的表面。通过在几个倾斜角度下的电子衍射获得了GOFT1单层的指纹图谱。最后，研究了这些材料在尼龙6基体中的潜在用途，观察到拉伸应力、拉伸应变和杨氏模量同时出现了异常增加。
