Description

Contain polyolefin resin of reduction-oxidation graphite and preparation method thereof
Technical field
The present invention relates to polyolefin resin and preparation method thereof, especially relate to a kind of polyolefin resin that contains reduction-oxidation graphite and preparation method thereof.
Background technology
Graphite oxide (GO) is to add the compound that water decomposition obtains after the powerful oxidation of the high graphite of crystallinity, can classify as the compound between graphite layers of covalent linkage.The preparation method of graphite oxide mainly is a chemical oxidization method, Brodie method for example, Staudenmaier method and hummers method etc.It has been generally acknowledged that on the Graphene reticulated structure of graphite oxide and contain epoxy, oxy radicals such as carbonyl, hydroxyl.Owing to this existence that contains the oxygen functional group, destroyed the reticulated structure of Graphene, influenced the transport passage of electronics and then influenced its electroconductibility, so the electroconductibility of graphite oxide is significantly less than the electroconductibility of Graphene.But graphite oxide is considered to the strategic starting point of mass preparation Graphene, and it can further use mechanical means, and like ultra-sonic dispersion in thermal expansion or the solvent, accurate two dimensional oxidation graphene suspension is stablized in preparation.Strengthen its composite performance through surface-treated then, and form Graphene, thereby realize that the nano level of Graphene in matrix disperses through reduction reaction.Graphene is that Geim of Univ Manchester UK in 2004 etc. find that after graphite peels a small amount of Graphene monolithic it has special characteristic electron.Realized in 2007 one flake graphite alkene is hung on the miniature support in air or in the vacuum, thereby broken traditional theory and tested the conclusion that is drawn.Graphene is except the electric property excellence, and the tensile modulus of Graphene (1.01TPa) is suitable with the single armed carbon nanotube with US (116GPa), its light weight, the big (2600m of thermal conductivity good (~5000W/ (mK)) and specific surface area 2/ g).Compare with carbon nanotube with the soccerballene of costliness, graphite oxide is cheap, and raw material is easy to get, and is expected to become the high quality filler of polymer nanocomposites.
Over nearly 10 years, a lot of about graphite oxide and multiple matrix compound report both at home and abroad, but graphite oxide whether monolithic layer is peeled off indeterminate.After 2004, along with the Graphene monolithic is proved at the stable existence under the conventional environment, and mechanically peel GO prepares the maturation utilization of graphite oxide technology, just truly realizes the nano combined of graphite oxide and polymkeric substance.The successful realization and the nano combined polymeric matrix of graphite oxide (perhaps Graphene) of report have PS (PS) at present; Polymethylmethacrylate (PMMA); Z 150PH (PVA), polycaprolactone (PCL) and some conductive polymers matrixes (polyaniline (PANI), polypyrrole (PPy) etc.) etc.Realize that polymeric matrix and the nano combined preparation method of graphite oxide have two kinds: direct graft process of polymkeric substance and in-situ monomer intercalation polymerization.The direct graft process of polymkeric substance is to utilize the effect of solvent or the polymer molecule insertion is had in the graphite oxide of laminate structure the formation nano composite material through physical actions such as mechanical shearings.This method is the traditional method of synthetic polymer nano composite material.Stankovich etc. (nature, 2006,442,282-286) in N ' dinethylformamide (DMF), PS is mixed with the ultrasonic isocyanate-modified graphite oxide of peeling off, add Hydrazine Hydrate 80 (H subsequently 2N-NH 2H 2O) to its chemical reduction, carry out injection molding hot pressing after desolventizing drying, made conductive graphene/vinylbenzene nano composite material.The electrical property of gained matrix material can be suitable with carbon nano tube compound material, and during the loading level volume(tric)fraction 0.1% of graphene film, the electric conductivity of matrix material can satisfy the antistatic standard (10 of film -6S/m), should value increase fast when loading level surpasses volume(tric)fraction 0.4%, 1% o'clock is 0.1S/m, and 2.5% o'clock is 1S/m.The blend in dimethylsulfoxide solvent of the graphite oxide of Z 150PH and esterification utilizes Hydrazine Hydrate 80 as reductive agent, has prepared Z 150PH/graphene nano matrix material.Document is arranged again, and (Macromolecules 2010,43, and 2357-2363) report reduces adding Hydrazine Hydrate 80 behind PVA and the GO solution blending, has prepared Z 150PH/graphene nano matrix material.When Graphene lamella content was 1.8vol%, its modulus is compared with pure Z 150PH had increased by 10 times.The oxygen functional group that contains of oxidized graphite flake layer is easy to the polar polymer interaction; (nature nanotechnology 2008 such as BrinSon; 3; 327-331) people's polymethylmethacrylate/functionalization graphene nano composite material that adopted Prepared by Solution Mixing Method, when the content of weighting material reaches 0.05wt%, its second-order transition temperature is compared with pure polymethylmethacrylate and has been improved nearly 30 degree.
The in-situ monomer intercalation polymerization be at present report prepare the less method of polymer/graphene (or graphite oxide) nano composite material.Exactly monomer solution and GO colloidal dispersion liquid are pre-mixed, monomer molecule is inserted the GO interlayer, drop into the initiator initiated polymerization then, make polyreaction see at the Graphene lamella and carry out, the reaction solution that obtains can obtain matrix material through handling.In the in-situ monomer intercalation polymerization process, because making, the expansion that the polyreaction heat release produces helps the spacing expansion between the oxidized graphite flake layer further peeling off, make that the dispersiveness of Graphene in matrix is more even.(Journal of Polymer Science part A:polymer chemistry 2010 such as Galland; 48; 692-698) people has reported that the graphite that MAO is handled joins in the ethylene polymerization still; As Primary Catalysts, MAO has prepared polyethylene/graphite alkene matrix material as the promotor catalyzed ethylene polymerization with bis cyclopentadienyl zirconium dichloride, and graphite is dispersed in the Vilaterm matrix with sheet form.The electroconductibility of not mentioned gained matrix material in the document.Domestic Zhejiang University (macromolecules, 2010,43,6716-6723) adopt the method for in-situ polymerization to prepare nylon-6/graphene nano matrix material.They are raw material with the graphite oxide, when nylon 6/poly closes, have realized the reduction of graphite oxide synchronously, but the mechanical property that just relates to the gained matrix material in the article does not relate to its electroconductibility.
Polyolefine is nonpolarity, is good electrical insulator, but friction or contact are charged easily, produces electrostatic and gathers, and processing products is caused bad influence with using.So big limitations polyolefinic range of application.The application at present prescription of antistatic polyolefine more widely is to add therein to prevent and eliminate polypropylene tape electrostatic additive, but this requirement to static inhibitor is relatively stricter.If in polyolefin substrate, introduce the weighting material of conduction, strengthen its electroconductibility, and then strengthen polyolefinic functionally and give its new performance, can expand polyolefinic range of application like this.
But to polyolefine, prepare its nano composite material the most effectively one of method be in-situ polymerization technology.This technology refers to olefin polymerization catalysis (is comprised Ziegler-Natta; Metallocene catalyst; Late transition metal catalyst and non cyclopentadienyl catalyst etc.) be carried on the carrier (graphite oxide or polynite), utilize this carried catalyst catalysis in olefine polymerization to prepare composite polyolefine material.Montmorillonite carrier catalyst olefinic polymerization that our seminar had once adopted the successful preparation of this method has obtained polyolefin/montmorillonite nano composite material, has applied for related patent U.S. Patent No. (application number: 200510009508.9,200910235504.0; 200910235506.X; 200910235507.4; 200910235505.5; 200910235503.6).Though graphite oxide and polynite are structurally similar, peeling off of oxidized graphite flake interlayer is more difficult than polynite, and the electroconductibility extreme difference of graphite oxide.So with the graphite oxide is raw material; The method of employing in-situ polymerization prepares the polyolefine/graphene nano matrix material of high conductivity, in this preparation process, can graphite oxide be reduced to Graphene it is scattered in the polyolefin substrate; And utilize the advantage of in-situ polymerization that graphite oxide or Graphene are dispersed in the polyolefin substrate; And the heat of polymerization that utilizes polyreaction to discharge is peeled off the Graphene lamella, and then it is functional to give polyolefine, promptly high electroconductibility; Can develop the high-performance poly olefin resin, this will be significant in practical application.
