We　report　the　liquid　exfoliation　of　an　anisotropic　layered　material:　KP15　to　form　KP15　nanowires　with　thicknesses　up　to　a　few　nanometers.　Meanwhile,　KP(15　)nanowire　is　the　first　kind　of　nanowire　that　can　be　prepared　by　liquid　exfoliation.　Moreover,　sections　of　the　KP15　nanowires　are　irregular　and　the　longitudinal　direction　of　the　KIP15　nanowire　is　along　the　direction　of　the　phosphorus　tube.　Those　results　may　indicate　that　in-plane　phosphorus　tubes　can　also　be　separated　during　exfoliation,　making　the　preparation　of　a　few　tubes　of　KP(15　)possible.　That　could　provide　a　basis　for　further　low　dimensional　physics　research.　(C)　2018　Elsevier　B.V.　All　rights　reserved.
