Description
Technical field:
The present invention relates to the grapheme foam field of compound material; Be specially a kind of grapheme foam/polymerization object height conducing composite material; Adopt the conductive additive of a kind of grapheme foam network of three-dimensional full-mesh as matrix material; Construct out a kind of matrix material, can be widely used in fields such as conducing composite material and elastic conductor with three-dimensional high conduction full-mesh network.
Background technology:
Graphene is the bi-dimensional cellular shape crystalline structure by the tightly packed one-tenth of monolayer carbon atom, is the basic structural unit that makes up other dimension raw material of wood-charcoal material (zero dimension soccerballene, one-dimensional nano carbon pipe, three-dimensional graphite).The unique crystalline structure of Graphene makes it have excellent electricity, calorifics and mechanical property, like its electronic mobility under the room temperature up to 200,000cm
2/ Vs, thermal conductivity is up to 5300W/mk, and Young's modulus can reach 1TPa, is considered to the desirable additive of matrix material.The exterior appearance of its two-dimensional sheet and super large specific surface area can produce more to enrich and contact more closely with macromolecule polymer material, have better than unidimensional carbon nanotube and strengthen the property.
The Graphene that present matrix material is used because adding to as strongthener, Graphene needs bigger consumption in the polymer materials, so can only be provided by the chemical stripping method.But the matrix material that is prepared by the Graphene that the chemical stripping method obtains has relatively poor conductivity; Be owing to graphite raw material in the chemical stripping process is peeled off by strong oxidation on the one hand; The Graphene that obtains has a large amount of textural defect and relatively poor conductive capability; Be because the Graphene that makes of chemical stripping method has less size on the other hand, add to advance behind the polymer materials between the sheet and sheet to be intercepted and open that the conductive path of formation certainly exists very big contact resistance by the polymer molecule long-chain.Graphene and high molecular polymer method of mixing mainly contain situ aggregation method and solution mechanical blending method at present.But when adopting these ordinary methods to prepare matrix material; Be difficult to the graphene film of two dimension is dispersed in liquid macroimolecule polymkeric substance or the organic solvent fully; Graphene film can be reunited in the high molecular polymer matrix usually once more; Cause uneven distribution, make performance of composites far below desired value.So how obtaining high-quality Graphene and graphene film is assembled into the successive conductive network will be the key that obtains high conductive graphene based composites.At present, chemical Vapor deposition process is one of effective ways that prepare in a large number the high quality Graphene, adopts three-dimensional porous foamed metal can also prepare the grapheme foam network of three-dimensional full-mesh as the template of chemical vapour deposition.If adopt the additive of this grapheme foam network, might develop a kind of general preparation method of high conductive graphene based composites as matrix material.
Highly integrated and intelligentized developmental stage has been experienced in hyundai electronics industry, and next important developing direction will be a flexible electronic device.The appearance of flexible electronic device will and be used the form of existing electronic product and produced great effect, and electronic product will no longer be an inflexible, but can be crooked arbitrarily and the tensile while do not influence use properties.The Application Areas of flexible electronic device will be very extensive, like the thin-film display that can curl, and softish electronics skin, the connection of joint of robot, and all wearable electronic products etc.Conventional rigid material such as metal and silicon etc. have good electric property; But do not possess snappiness and elasticity; Can not directly be used for preparing flexible electronic device, will be vital so develop a kind of type material that has good mechanical stability and conductivity simultaneously to the development of flexible electronic device.Graphene not only has very high specific conductivity, and has good mechanical stability and snappiness as the thinnest in the world two-dimensional film material, is the ideal material of preparation flexible electronic device.
