Amido modified graphene/class graphene MoSe2/ Bismaleimide composites and Preparation method

Technical field

The invention belongs to advanced compound materials science domains, are related to a kind of amido modified graphene/class graphene MoSe₂/ Bismaleimide composites and preparation method.

Background technology

Bismaleimide (BMI) resin has the characteristics that cheap, thermal stability is good, and it is multiple to be normally used for high-performance The resin matrix of condensation material.It is widely used in key areas such as aviation, transport, machinery, electronics.But span carrys out acyl The crosslink density of imines itself is higher, therefore especially crisp after its solidification, and some fine fisssures are easy tod produce in friction process Line, this just greatly limits application of the bimaleimide resin as friction reducing abrasion resistant material in many fields.Recently, research hair Now by nano particle be added in resin matrix can effective reinforced resin matrix frictional behaviour.

Two-dimentional carbon material and graphene-based material due to its excellent performance (such as good hot property, electrical property and its His excellent properties) cause the extensive concern of people.The presence of carbon material can increase substantially resin according to the literature The intensity and toughness of matrix, but also the extension of micro-crack can be effectively inhibited, therefore high performance friction material can be obtained Material.In particular, grapheme material is easy to shear due to its unique soft graphite layer, high intensity and on intensive shiny surface Characteristic, so that it is shown remarkable self-lubricating property, it also made to show huge dive in many fields as kollag Power.[the J.Colloid Interf.Sci.2015 such as Fan；452:98-108] by chemical method and electrochemical method in alkyl The graphene sheet layer that can in high volume process is prepared in imidazole solution, and finding can be significantly using graphene sheet layer as additive The properties of antifriction and wear resistance of enhancing alkylation pentamethylene, friction and wear reduce 27% and 74% respectively.Min etc. [Tribol.Int.2014；80:131-40] by situ aggregation method synthesized graphite oxide it is dilute/composite polyimide material, and It was found that the composite material prepared shows excellent properties of antifriction and wear resistance in brine.[the Polymer.2013 such as Shen；54(3): 1234-42] it has studied when graphene oxide content is only 0.05-0.5wt.%, graphene oxide/epoxide resin nano is compound The frictional behaviour of material；The result shows that compared with pure epoxy resin, the wear rate of the composite material of 0.5wt.% reduces 90.0-94.1%.Therefore, graphene or the grapheme material of modification can be widely used in polymeric matrix as kollag In.

After the discovery and research of graphene excellent properties, two-dimensional layer transient metal sulfide (TMDs) has weighed Newly start the interest by scholars and concern, because it can remove into class graphene-structured.Two selenizing molybdenums are similar to two sulphur Change molybdenum, is Typical Representative therein, the sandwich structure being made of two selenium atom layers and a molybdenum atom layer.It is adjacent Se-Mo-Se layers between be to be connected by weak Van der Waals force, therefore the friction coefficient between interface is relatively low.Zhang etc. [Micro.Nano Lett.,2015,10(7):339-342.] it is successfully made by mild hydro-thermal method using molybdate and selenium powder For two selenizing molybdenum nano flowers, and its friction and wear behavior is had studied as oil additive；As a result, it has been found that in base oil The two selenizing molybdenums of addition 1.0wt.% can reach best frictional behaviour.Based on the above analysis, two selenizing molybdenums can also be used as A kind of important kollag is added in resin matrix to enhance its frictional behaviour.Due to Van der Waals weak between layers Power so that two selenizing molybdenums are easy to happen sliding in process of friction and wear between lamella, and are easy to be formed between interface and turn Film is moved, this is considered as a key factor for reducing friction loss.Although graphene is a kind of widely used solid lubrication Agent, but due to its high surface energy cause its in a solvent dispersibility it is poor, this just greatly limits graphene in crowd Extensive use in multi-field.If can be compound by two selenizing molybdenum of class graphene and graphene progress, make the two that collaboration occur and make With the performance of the composite material of preparation will be better than one component of any of which.But the selenizing molybdenum of graphene/bis- is received at present The preparation of nano composite material and the research of frictional behaviour have not been reported.
