Performance of the performance of the composite of dimension not only with glass fibre and matrix is relevant with content, be heavily dependent on fiber with
The interfacial adhesion of matrix resin is strong and weak.Configuration of surface theory thinks that glass fiber compound material basal plane performance depends primarily on glass
The physical state of fiber surface, including surface area, roughness etc..At present, the enhanced method master in fiberglass reinforced plastics interface
If being carried out at surface to glass fibre using soda acid etching, coupling agent, plasma surface treatment, rare-earth treatment etc.
Reason, to improve the adhesion at interface between glass fibre and polymer.Soda acid can make fiber surface form some depressions or micro-
Hole, and then configuration of surface is become coarse, but they can to varying degrees drop low-fiber self-strength.In other words, from
Soda acid etching is not a kind of effective surface treatment method for the angle of mechanical property.Therefore, developing reaction condition is more heated
The functionalization method of sum is necessary for glass fibre reinforced composion/concrete, and it has turned into
One particularly important research direction of glass fibre field.
In recent years, research finds that fiber is wrapped up using nano particle can also effectively be protected high strength fibre and can carried
The mechanical property of high microsteping composite.Therefore, fiberglass surfacing construct nano material improve fiberglass surfacing product, it is coarse
Degree, is beneficial to improve glass fiber compound material/concrete interface adhesion.

（4）By step（3）The beta-schardinger dextrin for obtaining adds step（2）In the solution for obtaining, carried out using water-bath constant temperature oscillator
Treatment so that the glass fibre in solution bottom is rotated with the solution in container；
（5）Weigh 0.2-0.6 g ammonium persulfates add 10 mL secondary waters in, it is ultrasonically treated to be completely dissolved it；
（6）Under oscillating condition, by step（5）The ammonium persulfate solution for obtaining is added dropwise to step（4）In the solution for obtaining, benzene
There is in-situ oxidizing-polymerizing reaction in amine monomers, in reacting 24 h under room temperature condition, and then realize to glass in fiberglass surfacing
The functionalization of fiber；
（7）Solvent portions of the upper strata without glass fibre are outwelled in reaction after finishing, product is entered with ethanol and secondary water respectively
Row washing, removes the unsupported accessory substance in fiberglass surfacing；By the product obtained after washing be placed in vacuum drying chamber in
It is placed in after 50-70 DEG C of environment drying standby in drier；The scanning electricity of the glass fibre after the polyaniline functionalization for obtaining
Mirror figure is as shown in Figure 1.
Step of the present invention（1）Described in citric acid and aniline process for dispersing be ultrasonically treated or magnetic stirring.
