©　Springer　India　2016.　A　new　group　of　nanomaterials,　in　free-standing　form,　such　as　fiber/yarns,　paper/sheet　and　bulk,　made　of　carbon　nanotubes　(CNTs),　has　emerged　in　recent　years.　These　materials　have　shown　special　and　unique　mechanical,　thermal　and　electrical　properties,　with　potential　applications　in　various　aspects.　This　chapter　is　aimed　to　summarize　the　significant　progress　that　has　been　made　and　the　importance　of　potential　applications　of　these　carbon　nanomaterials.　CNTs,　of　single-walled　(SW),　double-walled　(DW)　and　multiwalled　(MW),　processing　strategies　(spinning,　filtration,　deposition　and　SPS),　morphologies,　properties　(mechanical,　electrical　and　thermal)　and　potential　applications,　as　well　as　their　inter-relationships,　will　be　presented　and　discussed　in　detail.
