Carbon fiber modification method and modified carbon fiber
The invention provides a carbon fiber modification method and a modified carbon fiber. The method comprises the following steps: providing a micro quartz dispersion liquid; taking a carbon fiber multifilament as an anode and an inert conductive electrode as a cathode, and respectively soaking the anode and the cathode in the micro quartz dispersion liquid; micro quartz is electroplated to the surfaces of the carbon fiber multifilaments in an electrophoretic deposition mode, and the surface-modified carbon fibers are obtained. According to the invention, the bonding strength between the carbon fiber and the cement matrix can be improved, and the slippage behavior on the interface is improved.
本发明提供一种碳纤维改性方法及改性碳纤维，所述方法包括：提供微石英分散液；将碳纤维复丝作为阳极，惰性导电电极作为阴极，分别浸泡在所述微石英分散液中；采用电泳沉积方式将微石英电镀到碳纤维复丝表面，得到表面改性的碳纤维。本发明能够提高碳纤维和水泥基体间的结合强度，改善界面上的滑移行为。
