Specific surface area and reactivity higher.For example, nano-Ag particles show stronger antibacterial effect, be not likely to produce tolerance and
With good biocompatibility, the antiseptic for commonly using is turned at present；Graphene, thickness in monolayer only has 0.35nm, is
The nano material most thin and most light in the world being currently known, possesses huge specific surface area, has in near-infrared region excellent
Photothermal characterisation, can show excellent anti-microbial property during with bacterial action, only be shown when being acted on cell or organism faint
Cytotoxicity, be it is a kind of not only have antibiotic property again with good biocompatibility nano material.
Graphene and nano silver antimicrobials is used alone all pros and cons, the unique design feature of many research and utilization Graphenes
As the carrier of antibacterial substance, formed with nano silver antimicrobials and carry silver-colored Graphene complex antimicrobials.Silver-colored Graphene is carried,
It is that silver nano-grain is grown in graphenic surface, anti-microbial property is realized and extended by slow releasing function, combines Graphene
Photothermal characterisation and silver nano-grain antibacterial advantage, solved in the past individually using dispersiveness of the nano-Ag particles in system
And stability problem, antiseptic is improve with other auxiliary agents in system with stability when bathing, the complex antimicrobials of relatively low-dose
Efficient Synergistic biocidal effect is capable of achieving, cooperative effect can not only overcome the problem of bacterial drug resistance, while also having low
The advantages of cost, high efficiency, nontoxicity, environmental protection.

Agglomeration, and its surface is in chemical inertness, and the interaction with other reaction mediums is weaker, is insoluble in water and common are
Machine solvent, therefore dispersiveness and Graphene of the Graphene in polymeric matrix are to play its antibacterial with the compatibility of polymer
The key factor of ability and other specific functions.The preparation method of current polymer matrix graphene composite material is mainly liquid
Phase blending method, melt-blending process and situ aggregation method.Solution mixing, the interface cohesion between dispersed phase and polymeric matrix
Intensity is relatively low, and residual solvent is not easyRemove.Melt-blending process, Graphene is easy to reunite in polymeric matrix.It is former
Position polymerization is Graphene and polymer interface bond strength and the improvement Graphene of improving maximally effective at present in polymer matrix
Dispersion effect in body, but the method complex operation, condition are harsh, are related to raw material various, and industrialization process control difficulty is larger.
