Method for modifying aramid fiber by combining plasma with dopamine |
| abstract |
The invention provides a method for modifying aramid fiber by combining plasma with dopamine, aiming at the problem of poor interfacial adhesion of aramid fiber and epoxy resin. The plasma pretreatment time is 2 minutes, and the concentration of the dopamine solution is 2 g/L. Removing impurities on the surface of the aramid fiber by using absolute ethyl alcohol and then drying; carrying out plasma treatment on the fiber; and (3) dipping the treated aramid fiber in a dopamine solution to form a polydopamine coating on the surface. The strength of the modified aramid fiber prepared by the method is enhanced by 1.4%, and the shearing strength of the fiber interface is improved by 20.6% in an epoxy resin composite material drawing experiment. The fiber treated by the modification method effectively improves the mechanical property of the composite material prepared by the fiber, and has wide application prospect in various fields such as military, building industry and the like. |
