Description

The hybrid material preparation method of a kind of fullerene micro Nano material and conjugated polymer compound
Technical field:
The invention belongs to technical field of material, relate to a kind of fullerene micro Nano material composite modification technology technique, particularly relate to the hybrid material preparation method of a kind of fullerene micro Nano material and conjugated polymer compound.
Background technology:
The micro-nano class carbon materials of low-dimensional is the ideal system of the physical propertiess such as the behavior of research electric transmission, optical characteristics and mechanical property, play an important role in the research field of the integrated circuits such as micro-nano electronics and opto-electronic device and functional element, for realizing its application extension, functional diversities, modification is carried out to low-dimensional nano carbon structured material, becomes the hot issue of current micro Nano material scientific research.Kroto in 1985 etc. find soccerballene C 60, there is the symmetry of height, the π-electron conjugated system of spherical delocalization, there are unique physicochemical property; The sex-limited behavior of the optical physics that soccerballene is unusual, electroconductibility, photoconductivity and light has caused the great interest of scientists, through the research of two more than ten years, there is the subject that organic soccerballene chemistry, soccerballene supramolecular chemistry, TXEndohedral Metallofullerenes, soccerballene pharmaceutical chemistry, soccerballene photoelectricity magnetics etc. are new, and in continuous development; (V.Georgakilas, V.F.Pellarini, the M.Prato such as Prato, D.M.Guldi, M.Melle-Franco and F.Zerbetto, Proc.Natl.Acad.Sci.U.S.A., 2002,99,5075) a kind of Ionized C containing porphyrin unit of reported first 60derivative can form nanotube, and this is presumably because that the π-π of soccerballene and porphyrin interacts, caused by electrostatic interaction self-assembly.Chinese patent CN1195103 and CN1215973 discloses and utilizes electrochemical method to make the aggregate electrophoresis of soccerballene in the nano-void of foraminous die plate, thus forms orderly micro-nano mitron and the method for micro-nano whisker; Chinese patent 1267342C discloses the C obtained by template contral radical polymerization 60the C that covalent intermolecular bond connects 60one dimension aggregate nano pipe, its radical polymerization to be adsorbed with monomer C 60the template of molecule maintains 2-4 hour, 1 kilowatt of ultraviolet lighting 0.5-1 hour in 400-550 DEG C under protection of inert gas.
But there is the problems such as the sample length-to-diameter ratio obtained is little, the bad control of purity, technology of preparing complexity in above-mentioned several method.In recent years, Japanese Laid-Open Patent 2005-254393A and 2006-124266A discloses near room temperature C 60saturated organic solution and the liquid-liquid interface liberation method preparation of Virahol there is the soccerballene C of single crystal structure 60nano whisker and nanotube, the method synthesis nanofiber there is single crystal structure, high length-diameter ratio and high purity (99.9%), but the method Problems existing prepares soccerballene C 60and C 70nanotube there is growth cycle long (more than a week), and reproducibility is poor, is difficult to extensive preparation; For these problems, Chinese patent CN100581998C disclose a kind of simple, reproducible, fullerene micro nanometer fiber of being applicable to preparing in a large number, having single crystal structure, high length-diameter ratio and highly purified solid or hollow without method for preparing template.Meanwhile, the research prepared about soccerballene micro Nano material gets more and more, as (M.G.Yao, B.M.Andersson such as Liu, P.Stenmark, B.Sundqvist, B.B.Liu, T.Wagberg, Carbon, 2009,47:1181) to pass through to use different solvents by simple method of evaporation, different vaporization temperatures prepares the soccerballene nano and micro materials of different dimensions, (the J.Y.Jeong such as Jeong, W.S.Kim, S.I.Park, T.S.Yoon, and B.H.Chung, J.Phys.Chem.C, 2010,114:12976) pass through to C 60add anti-solvent in-toluene solution and make soccerballene crystallization, prepare the fullerene nanomaterial etc. of different-shape.
At present, liquid-liquid interface liberation method has become prepares fullerene micro nanometer fiber and micro-nano wafer is simple, effective means the most, but can not only be confined to prepare on the fullerene micro Nano material (micro-nano whisker/micro-nano mitron/micro-nano wafer) of different structure for the research of soccerballene; Research finds that the nanostructure of soccerballene, fullerene derivate and soccerballene base is the good acceptor of electronics, can as receptor system application on the solar cell, but compared with carbon nanotube, the main shortcoming of fullerene micro nanometer fiber is that specific conductivity is lower, which limits its application, but find the C of alkali-metal-doped 60soccerballene has fabulous supraconductivity, with original C 60powder is compared, and has better electroconductibility; And the structure of fullerene micro nanometer fiber uniqueness, size are controlled, the feature that dissolves in some organic solvent, again can as the carrier of uniqueness and reacting field; Therefore fullerene micro nanometer fiber is modified to the paces in the epoch of having complied with.
Conducting polymer is the hot research problem of Material Field in recent years always, but during this type of conducting polymer eigenstate, Conductivity Ratio is lower, just has good specific conductivity after having to pass through doping, fullerene is good electron acceptor(EA), and containing the atom with lone-pair electron in conjugated polymer, is electron donor(ED), so available fullerene molecular dopant conjugated polymer, to increase its specific conductivity, report about the original fullerene powder of preparation and conjugation polymer hybridisation material emerges in an endless stream, as (Wang Q, Wang S, Li J, et al.J.Polym.Sci., Part B:Polym.Phys, 2012,50 (20): 1426-1432) such as Wang use C 60powder and aniline have prepared C as starting material by interfacial polymerization 60/ polyaniline composite material, at C 60with under the certain proportion of polyaniline, the electroconductibility of matrix material is good, I.Sapurina etc. (I.Sapurina, M.Mokeev, V.Lavrentev, V.Zgonnik, et al.Eur.Polym.J, 36,2000:2321-2326) pass through C 60be doped in polyaniline, add the thermostability of polyaniline and specific conductivity increases, but these methods all just make use of the character of soccerballene electron acceptor(EA), its electroconductibility is increased with its conjugated polymer that adulterates, this doping makes costly, if the fullerene micro Nano material prepared by original fullerene powder and conjugated polymer can be carried out hydridization, both can make the pattern of fullerene micro nanometer fiber/wafer that huge change occurs, meanwhile conjugated polymer is doped specific conductivity and is improved, such recombination energy obtains having brand-new photoelectromagnetism and the nano-hybrid material of mechanical property.
