Summary: This study presents a simple method to enhance the properties of electrospun nanofibers, by developing nanofibers using electrospinning followed by liquid infiltration and reinforcing the fibers with RF coating. The RF resin significantly improves the properties of PUN and reinforces the interface between fibers, leading to a remarkable improvement in mechanical properties. Coating with 20% wt/vol of RF solution achieves around 94% and 281% enhancement in tensile strength and modulus, respectively, compared to neat PUN fibers.

Summary: In this study, a new method was explored to graft glycidyl methacrylate (GMA) onto the surface of high-modulus carbon fiber (HMCF), which has extremely high chemical inertness. GMA was successfully grafted onto HMCF after acid activation synergized with ionization radiation, with a grafting degree of 22%. The hydrophilicity of the fiber was effectively improved after acid activation and grafting, and it showed good dispersibility in water. The surface structure of the fiber became highly disordered after grafting GMA. This work provides a new pathway for the modification of HMCF and is beneficial for obtaining high performance HMCF composites.
