    摘要： A single-walled carbon nanotube flexible transparent conductive thin film with a carbon welded structure and a preparation method therefor. In the process of growing a single-walled carbon nanotube by means of floating catalyst chemical vapor deposition, the concentrations of a catalyst and a carbon source and the residence time thereof in the constant temperature region are reduced, so that part of the carbon source decomposed by means of the catalyst forms an sp2 carbon island which is welded at the intersection of individual single - walled carbon nanotubes, and finally, a single-walled carbon nanotube thin film with an sp2 carbon island welded structure is formed. The thin film of the structure has better photoelectric properties, chemical stability and flexibility than the ITO thin film on a flexible substrate. The contact resistance between carbon nanotubes is reduced, the formation of tube bundles and a large absorption of light are inhibited, and a high-performance flexible transparent conductive thin film is obtained by designing and preparing the individual carbon nanotubes bonded by means of a carbon welded structure. The high-performance flexible transparent conductive thin film is of great significance for promoting the application of a carbon nanotube thin film in the field of high-performance optoelectronic devices.

    摘要： A method for transferring graphene nondestructively and at a low cost. In the method, a graphene is used whose surface is coated with transferring media and whose original substrate is an electrode, the electrode is placed into an electrolyte, and the graphene is separated from the original substrate by means of the driving force of bubbles and the gas intercalation produced on the graphene electrode surface during electrolysis. Then, the graphene coated with transferring media is nondestructively combined with a target substrate. The transferring media is removed so as to transfer the graphene to the target substrate nondestructively. The transferring method results in no damage or loss with respect to the graphene and the original substrate, and the original substrate can be re-used. Furthermore, the method is easy to perform, works quickly, is easy to control, and is pollution-free.

    摘要： Provided is a method for continuously preparing graphene oxide nanoplatelets on the basis of an electrochemical treatment, comprising using a continuous graphite product such as a flexible graphite coil, strip or carbon fiber wire as a raw material, successively subjecting same to two step treatments, i.e. an electrochemical intercalation and an electrolytic oxidation stripping, under the drive of a feeding device, and stripping same into the graphene oxide nanoplatelets. The electrochemical intercalation is in a concentrated acid, using a graphite material as an anode and energizing under a soaking condition such that acid radical ions enter into graphite interlamination under the drive of an electric field, to form an intercalated graphite continuous material with Stage I or lower intercalation. The electrolytic stripping is using the intercalated continuous graphite material as an anode, energizing in an aqueous electrolyte solution to perform electrolytic stripping, and performing oxidation stripping on the intercalated graphite by utilizing oxygen generated by electrolyzing water displaced to interlamination, to obtain graphene oxide. The method has the following advantages: a product does not contain a metal impurity, the oxidation degree of graphene is controllable, the process is continuable and automatable, and the method is safe and has low emissions, etc.
