Description

A kind of nano silver wire functionalized carbon nanotubes static inhibitor and preparation method
Technical field
The present invention relates to a kind of nano silver wire functionalized carbon nanotubes static inhibitor and utilize the method for carbon nano tube surface grappling platinum crystal seed growth in situ nano silver wire, belong to static inhibitor technical field.
Background technology
In recent years, along with macromolecular material in every field widespread use, thereby macromolecular material functional proposed to more and more many requirements, wherein general engineering materials is as polyimide (PI), polycarbonate (PC), polyetherimide (PEI), polyether-ether-ketone (PEEK), due to mechanical property and the resistance toheat of itself excellence, at the aspects such as component of medical equipment, chemical industry equipment, electronic installation and automatization, use in a large number.Yet it is as electric poor conductor, when material friction or electron device produces in environment for use electric charge cannot be leaked in time, while running up to a certain degree, will produces static, and then cause human injury or cause electronic product to damage.Therefore reducing material resistance reveals electric charge in time, prevents the active demand that above material is proposed that becomes of static.
Static inhibitor as addition type mainly comprises carbon system and metallic stuffing system, from adding the conduction property of material itself, adopt metal matrix static inhibitor best beyond doubt for the specific conductivity that improves matrix material, but the threshold concentration of metal interpolation material is larger, generally in 50% left and right, therefore the amount needing is larger, larger to cost increase, the a large amount of interpolation of metal matrix functional stuffing and the consistency of the two are poor in addition often has a negative impact to forming the mechanical property of matrix material, moreover the density difference of the two is apart from large, affected again the stability of matrix material, therefore metal one-dimensional nano line is more easily formed to conductive network under low concentration in matrix external phase, thereby greatly reduce the consumption of metallic stuffing, weaken the disadvantageous effect to body material of bringing due to filler.Carbon is that carbon nanotube in static inhibitor attracts tremendous attention in the field of study at present, it is that a kind of radial dimension is nano level, and the carbon material of the cannulated constitutional features that axial dimension is micron dimension, has high-modulus, high strength, is considered to desirable reinforcing function filler.The similar graphite of carbon nano-tube conductive energy, and when making it add in matrix, its outstanding length-to-diameter ratio is more conducive to form the network structure of chain type than graphitized carbon black in matrix external phase, but its main drawback is its bad dispersibility in polymeric matrix, need surperficial organic modification to improve surface polarity, dispersion and the interface binding power of raising in polymeric matrix, gives full play to the two-layer effect of its reinforcement and functionalization.Carbon is that static inhibitor another one shortcoming is composite products color owing to reaching functional requirement, thereby addition affect greatly material true qualities, therefore needs assurance to give the addition of the functional prerequisite decline of body material low-carbon nano pipe.
In view of the outstanding advantage of above bi-material, by obtaining the composite antistatic agent in conjunction with both advantages at carbon nano tube surface growth in situ nano silver wire, for it, preparing transparent electrode material and antistatic material provides and has avoided a kind of solution of shortcoming separately.
