Gravitational Faraday Rotation (GFR) is a frame-draggi ng effect induced by rotating massive objects\, which is one of the import ant characteristics of lensed gravitational waves (GWs). In my previous wo rk\, we calculate the GFR angle \;of GWs in the weak deflection limit\ , assuming it is lensed by a Kerr black hole (BH). We find that the GFR ef fect changes the initial polarization state of the lensed GW. Compared wit h the Einstein deflection angle\, the dominant term of the rotation angle& nbsp\;is a second-order correction to the polarization angle\, which depen ds on the light-of-sight component of BH angular momentum. Such a rotation is tiny and degenerates with the initial polarization angle. In some crit ical cases\, the GFR angle is close to the detection capability of the thi rd-generation GW detector network\, although the degeneracy has to be brok en.
